Back in the 80s, my friends and I used to go out for all you can eat Buffalo wings or ribs. When an "all you can eat" restaurant sees a table of young guys, they often use a strategy of having the waiter disappear so you can't get another order right away after you finish, slowing you down. My friend figured out a way to defeat this. One time when we were eating all you can eat ribs at Beefsteak Charlie's, he finished an entire rack of ribs before the waiter finished serving the table. When the waiter started to walk away from the table, he said "Can you bring me another rack?"
