I’m with ya.. I never tip baristas in the drive thruSo let them get angry. Do you think guaranteeing them $30/hour would make them be better servers? My experience locally anyway is that servers do their best. I’ve maybe had one over the past several years who wasn’t on the ball and she was tipped accordingly. Eventually they’ll either figure it out or seek a different job. Tipping is a great capitalistic idea. If you don’t like it, go to the drive thru.
