Doesn't matter if
you do. The law does.
And the law specifically has sympathy for the waitstaff because of the tendency of workplace standards to be uniform across a particular area and industry. When all the steel mills in a given town are equally dangerous, and all the management is equally unresponsive, the result is the creation of health and safety laws precisely to give an individual worker the authority to deal with an individual mill owner from a position of relative equality.
Saying that I can get a job elsewhere doesn't help much when all the workplaces are equally dangerous. But since there are more workers than there are bar owners, we can simply get together and vote safety standards into place. If you don't like that, you can always sell the bar and re-open a different one where the laws are different.
