Tipping is dumb. I do it, but I hate it. I'm already paying an agreed upon price for a service or product that I can't negotiate. Why should I also help pay your employees wages?
I always tip the barber.The one non-traditionally tipped person I tip is the lady who cuts my hair. She owns the business, and has no employees, so I assume that she's built the cost for all she needs, but it's so damn cheap ($11.50) and she always does a good job so I tip a few bucks to make it an even $15.
Or they order 50 percent more than what they need and leave you with a pile of materials in your yard that you paid for and have no way to get rid of.
Should I tip a house painting crew?
The only people i've tipped for doing work around my house is when I hired Two Men and a Truck to move in a large safe. It was about 100° and 90% humidity that day and the safe weighed ~900 lbs. I think the one guy may have dislocated his shoulder trying to get it through the door.
I didn't really think about tipping the tree guys after the derecho. Seems like I paid them enough as it was!
