Some thoughts

Tonight at the end of my shift, a woman who is known to be homeless and a little crazy came into the store. She had a lot of things piled up on a wheeled cart and began asking about our food items and if we had any oatmeal left. We didn't. She continued to talk to me and then asked if she could use the bathroom. I told her the bathroom is for customers only. She then informed me that "they all" let her use it. Since I didn't want to start an argument, I went ahead and gave her the key. I didn't want her to use the bathroom because I knew she would be in there for a while and it was close to closing time, but also because of the principle of the matter. It is a customer only bathroom, and we can't let everybody that walks by use it. But, what if she had to go on the street or in the bushes because I didn't let her use it...how nice is too nice, and when should you just let things slide?
