This discussion around what to tip hides an employment system that values employees to the point of underpayment and poor working conditions.

Perhaps you should instead frequent establishments where tipping is not expected because the employees are paid a proper wage.

That way, you don’t have to argue about tipping your bartender too much, or not enough, instead you can focus on drinking a superbly crafted concoction of your choice.

I’ll also note that tipping is not universal.
