Hands Off!
This story involves a waiter that got too chummy with the OP and his friend. The server congratulated the OP for finishing his cocktail, much like a mother would congratulate her child for finishing their plate of broccoli. We get that the waiter was trying to be playful, but you were speaking to a grown man!
But the worst had yet to come. When the friend asked for a lime wedge for his drink, the waiter returned with the wedge lying flat on his palm. Then he proceeded to toss it onto the table, as if he were saying “Heads up!” If we didn’t know any better, we’d think the waiter was intoxicated while on duty.
