However, you can see nothing is actually going into the bin while she is doing it. 140599 (Season 1, Ep 10 - 'All About Steve'): At the convention when we first see Roger and Hayley, they pass a booth that says Costume contest registration. There is also a few people around, a poster and a movable wall. The very next shot is more of a close up of the two and the background has changed dramatically. There is now about 4-5 different stalls behind them and no sign of the previous one or the poster and wall.
