Very sneaky hidden fee, no way to remove it or adjust service charges, and even ask for additional tip on top of service charges for the app.
A non optional £.79 charge to pay through it and no way to dispute the added cost not advertised by any of the merchants.

Will never use any restaurant again using this rip off app. Next iteration will probably have a tip for the software developer.

Dined at Big Mamma using Sunday, they tried to charge an additional fee for the privilege of using their terminals which was not disclosed prior to dining. When I complained, staff told me there was nothing they can do, the rate is set by Sunday and Big Mamma has no control over it - a quick Google showed that Sunday is owned by the same people as Big Mamma, so clearly just a ploy to get more money in their pocket. Has put me off Big Mamma, and where I see Sunday now in a restaurant, I try to avoid.

Pay a fee to pay my restaurant bill? No, thanks.

How it works: a restaurant will ask you to pay through the QR code and the app will add a fee to your bill. Usually your bill already includes a service charge. So you are getting charged service charge + the app fee.

Warning: if you go to any of the Big Mamma restaurants you'll be asked to use this as the founder of the Big Mamma group is also the founder of the app.

I plan to avoid any restaurant using this.

I used this app at Strada Southbank as I wished to pay quickly in order to catch a train. It creates a very confusing bill that gives the impression service charge is voluntary and asks for a specific tip. As a result I tipped twice….something which wasn’t clear until the payment had gone through. I asked the restaurant to sort this out but am still waiting for it to be resolved.

$5 hidden fee to pay a bill at my table. No mention on the table QR sign of the fee to pay. Didn't see it listed when I reviewed my bill prior to paying. Then a $4.99 fee appeared on my emailed receipt from Sunday. Ruined a positive meal experience with a "more than an ATM fee" charge that was not disclosed prior to me paying. I felt scammed. Will not return to this restaurant and I'd been there a lot.

Horrible experience. When building a product and expanding to other countries, the culture of the country should be taken into account. Never using this app again.

Simple & quick. Split the bill with a friend. All through the QR code link. Apple pay integration. Took 10 seconds to pay. Service charge £0.49
Fantastic product.

Wait - save my time by using this app?
Did you mean, save your staff from doing work by not handling customers or money?
And I need to pay you extra?

I scanned the QR code on the table to pay the bill as told to by the staff, expecting a normal online/app transaction. However, the Sunday App charged an additional "checkout fee" on top of the service charge, which couldn’t be removed! Then it asks if I want to add a tip! Literally fleecing me of money on an already expensive bill.

The staff in Big Mama Group are notoriously slow and avoid you when it comes time to pay, so you have to be quite determined to get hold of them. It must be a training tactic to force you to pay via QR code and pay over the odds. Also I’m sure this ‘checkout fee’/‘tech fee’ is actually illegal and I’ll be reporting them.

The app expects customers to pay the same service charge as before, plus an extra fee for the supposed “convenience,” despite reducing the service needed and experienced per customer. It’s simply unacceptable.

I feel really taken advantage of and disappointed. I've decided not to revisit any restaurant that uses this app and imposes such extra charges.

I hate waiting to pay at the restaurant. Sunday is truly a revolution because there's no longer a need to wait for the waiter to bring the payment terminal.
Yes, it cost me 20 cents, but I paid and leave in 30 seconds.
According to me, the scandal is waiting 20 minutes behind 10 people at the till.

Very efficient way to pay. Much more simpler as a guest. Loved it.

Rip off fees charged to customer paying in restaurant to pay their bill. Any fees should be responsibility of the restaurant.

No option but to pay a £3 fee on payment - for no benefit. Outrageous

Charged £2.99 to use the app. We split the bill 5 ways without realising. So we spent £15 in fees!

When it came to paying the bill, I was told to use the QR code on the table. That took me to an app (Sunday App) only to charge me extra - what was called a "checkout fee" on top of the service charge - for the privilege of paying the bill without using a card machine! That's unacceptable and nonsense! I will never go to a restaurant that uses this app and pay a checkout fee!

My restaurant bill was more expensive because this app added a charge to pay with credit card. Asked the waiter politely to remove this charge and to pay in cash instead.

Charges you to pay a bill, absolute joke of a company.

If in a restaurant (or wherever) that uses it, tell them you want to pay on their card machine and have the service charge removed off the bill due to them using this app.

Don't return to anywhere that uses this app, they don't give a damn about you as a customer, so let them go under.

Pay fees to pay your bill and avoid social interactions
