I used to work in retail, and let me tell you... I got PISSED at customers that came in 2 minutes before the store closed, and insisted on big orders being carried out. Nothing bothered me more than staying well past the end of my shift to help these people. I am now sensitive to this, and won't enter a restaurant after a certain time, and won't enter a store after a certain time, depending on what I need and how long I think I would be there. I am curious as to what other people think is okay regarding this? Do you have any rules or regulations regarding entering soon-to-close businesses?
