People busy having a good time, don't typically stop and look for a trash can. It's unfortunate but just part of business as usual with a large event of ANY kind.
@donnatella:
Even if I have a good time at some event, I don't just say, it's time to go, think I'll just drop this bag/cup/beer can or whatever right here where I'm standing. Of course, I always return my cart too, so maybe that's just me.Â
