I went to the British Museum yesterday to see Hadrian: Empire and Conflict, which was pretty good. I booked online, and received the confirmation email below. I turned up at the museum, went to a self-checkin kiosk and it asked me for my order confirmation code. So what did I type in?
Right, I type in the huge number next to "Order confirmation". Unfortunately what it really wanted was the collection code, in small. It didn't ask for that. It asked for the order confirmation code. The one not in the huge font. The one not in bold. No, I'm not sure why there are two codes either. It fell to one of the humans at the desk to tell us this. As I'm sure he has to do every few minutes every day of the week. Moral of this story: think careful about what you call things and make humans happier.
