Since you are not able to set your own rate prior to settling the bill, you are not selling your labor to consumers at all. You are depending on the arbitrary mood of the consumer to possibly offset the insufficient wage your employer is paying you.

Correct. The rate is 0% and it is up to the charity of the customer to do anything more since, as you say, there is a lack of an enforcement mechanism. I am happy you are able to manage your income on the expectation of tips, but many tipped workers are not in your enviable position.
