I got an amazing deal on some carry on luggage this morning at the store I work at. I usually don't work with customers but everyone, even the overnight crew, was expected to be there this morning. Except for one incident where some blonde woman got arrested for shoplifting, nobody seemed to be causing any trouble or acting like maniacs.
Usually at my store the crowd is pretty sane comparatively speaking. I don't know if it will always be that way but I hope so. Maybe part of what helps is that many of the sale items are heavy bulk items like trampolines and pool tables in boxes, etc. that they can't really pick up by themselves and run with.
