We had that too, we asked her where the organisers booth had been moved to as it wasn't where it was supposed to be on the map and got an 'I don't know I'm busy' before she hurried off. Very very rude. And again from one of the guys at the Sales Desk queue, we got an 'I don't know, this is my first day' and then wandered off, didn't offer to find someone else to help or anything.
The red shirts have been wonderful, you can tell they are experienced and helpful. Fetching chairs for my friend who has a stick and has trouble standing or walking fast and making sure she was okay. Unlike the other attendees who nearly knocked her down repeatedly by pushing past and generally shoving. Not impressed by the layout or by having two floors only accessible by crowded lifts that you wait for for ages.
Exactly, I thought it was rude. If she had just said "I'm very sorry I don't know" and then directed us to an area where we could have asked someone else then I wouldn't have minded. The guy on the table with a guest was more helpful and even admitted he didn't know where one guest was, because he'd been sat at the same table all day. I liked that because at least he was honest and nice about it, but he did atleast offer us a place where we could go and ask someone where the last guest was :)
