I've noticed that being nice to someone can help you in so many ways. First of all it's just good to be nice, to smile, to strike up a casual conversation, it puts you and the other person in a better mood. Recently being nice has helped me get some "extra" things. TWICE I was at a thrift store buying used books and the cashier reduced the price just because, and these were different stores. I was nice to them and I think that helped. I was at Tim Horton's the other day buying timbits and the lady gave me TWO extra ones, yes I counted. We chatted at the counter and when she handed them over she gave me a wink so I had a sneaking suspicious she might have given me an extra one. Today I was coming home from work starving and stopped at Subway (over an hour to get home, I couldn't wait) and ordered a sub. The girl and I chatted and joked about the Canada hockey game and guacamole of all things and I noticed the girl gave me extra meat and cheese. Yay! Last summer I even once had a girl buy me a drink at a bar because we were both waiting at the same time and she was getting drinks for her friends.
Be nice, be funny, be polite, smile because really it pays :)
Have you ever had things like this happen?
