Usually employees who are tipped get below minimum wage. The problem is some of the states allow for this practice where employers don't have to pay them the minimum wage.
Example: the waiters at my friends hookah lounge were paid 10% of their checks, not including the gratuity automatically added, whatever they got tipped additional handed to them by the customers was theirs and they didn't report it.
The problem was, they were working 12 hour shifts, and on Mondays-Thursdays, it was pretty dead and they would be lucky to have over $1000 in sales those days (if their total was $1000, they were paid $100). Now on Fridays-Sundays, they were sometimes bringing in $5000-10000 in sales, but bad weather could easily cripple that.
Hookah lounge workers got super fked by Covid because obviously based on the hookahs being shared by multiple people, hoses/hookahs being shared by multiple customer groups (only the tips are disposable), no one wants to go out for hookah anymore because it's definitely an easy way to catch Covid. I used to be concerned in the past about TB infections from shared hookah.
