I've been going here for years. Never been required to pay a certain tip amount. I pay the posted price and give a tip based on the service received & what I can afford. Never had an issue.
If the tip is not included in the price, I don't see what is the problem to leave it separately.
Theres no problem with leaving a tip separately... However if there is a required amount that should be posted or included in total... Not a mandated thing after the fact...
