It mostly bothers me when I just order 1 entree and a water. At one place that might cost $10, and at another place it might cost $30, and all the wait staff did was carry a plate from the kitchen to me in both cases.

It doesn’t seem fair that the wait staff at the more expensive place gets tipped more than the less expensive place just because of an arbitrary custom.

The extra cost of the expensive meal is mostly due to ingredients, the cooking process, the location, and maaay slightly more complicated table setting.
