I get confused on tipping when it comes to "services". When am I "supposed" to, how much? We went on a fly fishing expedition this summer, it was $150 each, and then we were supposed to tip??? What the?? When we went white water rafting, it was mentioned that we were supposed to tip our guide? I guess I don't get why we're "supposed" to tip people for those kinds of things, especially when we're already paying a couple hundred for the trip itself. Now I worry that I was supposed to tip my snowboard instructor last season, or my bike fitter. I think it all started with the fast food restaurants leaving tip jars on the counters...now everyone thinks they're entitled!
