waitstaff isnt paid that much hourly. Its generally on the order of 2-3$ per hour.
edit: since im being downvoted i assume someone disagrees - here is a source:
from nolo.com:
>Employers must pay tipped employees at least $3.23 an hour in 2016, $3.38 an hour in 2017, and $3.52 an hour in 2018.

Technically you can sue your employer if they wont pay you the difference if you dont end up making enough in tips to end up at or above minimum wage - in practice however, suing your employer is generally not a great way to stay employed

Only way I know round UK min wage is to be self-employed, or one of the fake "self-employed" like some delivery drivers have had to become. Surprised the IR haven't slammed the door on that little scam yet.
That said, it's not uncommon to get at least minimum wage.
