This happened to me a few years ago and I still wonder if I was rude. Please settle this for me E-Hellions.
I went on an international trip with my boyfriend and his son-in-law and daughter. We were on a ferry boat going to another country. I bought an internet card so I could read my E-Mail as this was a long trip. I tried using the Internet and it was so slow and frustrating, I gave up. My BF's daughter was bored so I let her use the Internet card so she pass some time. I don't remember the exact wording I used when I handed the card over.
A little while passes and I see the daughter sitting with her husband. I said, "did you use the internet?" She said no that it was too slow, so she cashed in the Internet card. I said, "that money is mine." She gave me back the cash but was miffed at me. My BF agreed with her that I was rude to ask for the money.
