My former employer still gets set for a big day, but it never comes to fruition. Sometimes it’s a little slower than usual. But, that still means non-stop from about 4 till 7 (central time). The delivery times are usually about an hour, with 5 or 6 drivers going. But, he has extras on call, they usually come in and do things like fold boxes and extra cleaning during the rush. The extras are by their choice, they don’t really WANT to deliver, but they will.
It sounds strange, but it works. Dine-in is usually a bit down, only 2 televisions in the whole place.
