Cheap Date

I went out with my friend (not girlfriend) Sandra over the weekend. We went to a movie, (The Queen, which was good), and ate out. I have always suspected she was a bad tipper, and I had my suspicion confirmed when I saw her throw a dollar bill into the folder before we left the restaurant. Her bill was probably 12 bucks or so, and the service was fine, so the tip should have been at least a couple dollars. Sandra does not make a lot of money, and she is a single mother, but I believe you should not eat at a full service restaurant unless you can afford to leave a proper tip for good service. I had suggested fast food if she didn't have much money, but she chose Red Robin. Go figure.
