The bar-to-table problem
Take one example: $36 in cocktails at the bar. $180 dinner in the dining room. One combined check for $216 and a single tip line. You leave $43.20 at 20%, but five different staff members touched your table tonight: bartender, server, busser, food runner, host. Where does that $43.20 actually go? (Dividing the bar portion among the group is a separate question — see how to split a bar tab fairly.)
Federal law lets restaurants require staff to share or pool tips with other eligible employees, and it sets no limit on how much each person contributes to a valid pool. So your tip may not stop with the person who hands you the check. It can flow through a distribution system that most diners never see.

Understanding how tips flow through restaurants changes how you think about that single tip line. Federal rules set the limits, and the math is more structured than you might expect.
