OK, so I go to Colorado last week to ski for three days and while I'm there I go to an outfitter's shop to rent my skis, poles, and boots. An employee has me take off my shoe to measure my feet, gets the right sized boots, and then adjusts the ski fittings to the boots, all of which took under 5 minutes. I have never heard of tipping for this sort of thing, but when they ran my credit card there was a line on there to tip if I wanted to. Employees didn't say anything about it or act like I was supposed to, but I was still kind of surprised to see it on there. I did not tip for that because I always assumed the fitting of boots is a standard part of the rental fee. Who here thinks I should have tipped?
