I was out with some girlfriends in a bar recently knocking back a few glasses of wine, when this guy approached us and started chatting to me. While I wasn't interested, I was polite enough and answered all his questions before giving him the brush-off. However, he then asked for my phone number, saying he was really interested in seeing me again. I told him I didn't want to see him again and refused to give him my number, but some of my mates thought I was being rude. Was I rude for not handing over my digits?
