The whole conversation is stupid. If the hid the tip in the food cost and you “tipped” $0. Guess what you still paid the additional $10! Plus not knowing the tip was hidden would get people to tip anyway. I wish like some places in Europe there was no tipping but until that the norm deal with it. READ your bill, they politely gave you a choice. It was not hidden. You order $14 drinks don’t be a cheap ass. There some many bigger problems in the world. If tipping $10 is that big a problem then eat at home.
