If I started explaining exactly what is so complicated, I'd be here all day, so I'll just mention the current confusion:
I've just booked "guaranteed entry" tickets for Victoria Park tomorrow (no, not just to see if Boris is still up there), and the blurb says "tickets should be printed no later than 24 hours before the event." Well, the "event" starts at 11am tomorrow, and given that it was already 11:02 when I read those words, I'm not sure if I'm screwed or not.
We don't own a printer so I've just booked a screen round at the library to go and print out these tickets. Just one question, on second thoughts make it two: Have they really programmed their ticket-bar-code reading machines to read the time the ticket was printed? And WHY THE FUCK DOES IT MATTER WHAT TIME I PRINT THE FUCKING TICKETS?
