I specifically asked our server about the upcharge and she told us that the server does not receive the entire $5 or $10 charge. It is split with bar and head server, etc.
So be sure to tip in cash or on the tab, whichever you prefer. The extra amount you give in cash or on the bill goes directly to your server.
This is also true with the 15% that is added onto your bar bill. It is split 5% to server, 5% to bartender, and 5% to back bar.
So, tip what you want this person to have.
P.S. Louise is awesome in Palo!
