Dear all,
Last week I had lunch with a work friend & we went to grab a coffee afterwards. She then announced to me in the cafe that I owed her, so I informed her I'd brought coffee for her the time we met before, but she said "No, you owe me for rescheduling", I didn't want to make a scene so I paid. This isn't really an issue about the money, but rather I feel really shocked by such behavior and like I don't want to meet this girl again. Am I being unreasonable here?
