A dark humour joke
A dark humour joke! " Full Programme Open For Bookings on 20 August, noon". I was with my account opened and ready to book at 11:58 am, on 20 August. Exactly at 12:00 their website crashed! When it came back some minutes later, there was nothing left to book! What a joke! The Old Admiralty Building (OAB),for example, was fully booked while the site server was down! Liars! The 10 Downing Street never even opened the "enter ballot" feature! It must be just for friends and family! No any chance! You go back to the other houses and site to book a visit and it is already all booked while the server was down! This is a public relations chicanery! What a shame! But they have none!
