I used the website to buy a ticket recently for the first time
I picked my seat, to be next to a friend, but then due to being a "dense ****" pressed the back button to check I'd got other details correct before I paid...I had so went to buy it...only I couldn't because it now wasn't available
Bugger
So I picked another one nearby when it dawned on me that it was highly unlikely someone had bought that single ticket in the few seconds I'd left it. So to test that theory I clicked on another one (without going back, just on the same page as if I was undecided...in the same way you can when buying flight tickets) Now neither of the tickets was available to me!
I double checked by clicking on a memorable pattern of other tickets nowhere near me...now I wasn't able to buy any tickets I'd clicked on
This was vaguely interesting, but still meant I couldn't buy the ticket I wanted
I kept reopening the page to try, but it was over 3 hours before it reset itself and the tickets were available to actually buy.
So if you try and buy tickets and notice someone has spelt "****" in bought seats in a quiet section you'll know it's me having a free play again !
