At least stay open til 6:00. Here's a true story why you should. I work til at least 5:00 everyday. It was my anniversary last week. My plan was to run out on my lunch and pick up flowers for my wife. The local florists in town are only open til 5:00. Well, I got extremely busy and time got away from me...I never made it out to lunch. When I left work at 5:30, my only choice was the grocery store on my way home. Not what I wanted to do, but at that point I was left with no choice.
