I think it’s insane too. I understand that tipping goes (theoretically) to the waitstaff, but I have a hard time tipping $1 per $4.50 bottle of beer handed to me. If it’s more complex of a drink than x and coke, sure it took their time.

Tipping table service used to be good amount only not drinks and tax. Now it seems to be on top the final total with 20% being expected.
