Absolutely disagree with this description of the job a waiter does.
A waiter orchestrates and coordinates the experience for the diners they are looking after.
They slow down orders to stop the kitchen getting overwhelmed.
They upsell on the menu in a way that is helpful and informative.
They understand the dietary requirements of guests.
They hold complex orders in their head and drop the right plate to the right person.
They know the flow of a table and engage or back off as appropriate.
Don't undervalue a role that can make a night out magical or a simple coffee memorable.
