Michigan server who got $10,000 tip says she was fired in ensuing dispute

I get that- and thats part of the 'formula' - wait staff are usually well below min wage for hourly + tips.

Cooks generally above $15/hr whereas wait staff ( when i was doing ) was like $2.13/hr plus tips.

But even with the wage disparity, am i going to a restaurant because the servers are nice or the food is really good?

That's true, but the kitchen staff gets paid the same regardless of if they do a good job that day/night or not. And while you may go/not go based on how good the food is, the tip for the wait staff is supposed to be based on the service they provide, not the quality of the food.
