Tipping etiquette.
It’s hardly a world exclusive rant, but my current beef is the suggestion that the fixed percentage we tip should rise due to economic pressures.
This is economically illiterate as if prices go up the overall value of a tip as a fixed percentage goes up anyway. So increasing the fixed percentage when prices are high is effectively a double increase.
I will always pay a fixed service charge of 12.5%, but rarely tip on top of service. I would struggle to justify a 20% service charge.
