"Minimum wage has nothing to do with wages for servers/ wait staff. You are misinformed."
I'm sorry but it's you that are misinformed. Things vary by State.
Yes, in many states, tipped staff are allowed to be paid a lower minimum wage than non-tipped staff. However, even in these states, the employer is required to bring their wages up to the minimum wage for non-tipped staff if they do not receive enough in tips.
Then, in other states, tipped staff are required to be paid the same minimum wage as non-tipped staff.
Most British people tend to visit NYC, Florida or California.
Let's look at the relevant state laws:
In NYC, tipped food service workers minimum wage is $10.65 per hour and employers must make this up to $16.00 per hour if the employee does not receive enough tips.
In Florida, tipped employees minimum wage from October will be $9.98 per hour and employers must make this up to $13.00 per hour if the employee does not receive enough tips.
California is different in that everybody receives the same minimum wage regardless. That means that tipped staff receive the same minimum wage of $16.00 per hour and then get tips on top of that.
Some areas of California have even higher minimums. For example, the minimum wage in San Francisco will be $18.67 per hour as of 1st July. In Los Angeles city it will be $17.28 per hour.
Then those employees working in most fast food restaurants (eg McDonalds etc) now get a minimum wage of $20.00 per hour
