When you arrive you stand in a double-line (assuming that your fellow customers realize this is a double-line) and while standing in line are asked for your order by an employee who writes it on the back of a paper bag and hands it to you. If you don't finish giving your order to him by the time you reach the end of the line, he'll hand the bag with the half-finished order over to you and you can hand that to the cashier and give her the rest of your order. Otherwise when you get to the end of the line, you simply hand the paper bag over to the cashier who enters it all in the system and takes your money. Then you are given a 3 digit order number.
Next you go over to a pick up window (located 25 feet to your left) and wait for your order number to be called.
HOWEVER, if you ordered JUST a salad you need to go to a different pick up window (located 20 feet to your right and behind you) to wait for your order number to be called.
HOWEVER, if you ordered hot food AND a salad in the same order, then you need to wait somewhere between these two pick up windows because the salad will come out of one and the hot food out of the other.
HOWEVER, if you ordered a drink with your salad AND hot food, the drink will appear at the hot food pick up window, while only your salad will appear at the salad pick up window.
HOWEVER, if you ordered only a salad and a drink (no hot food), then both of those items will come out of the salad pick up window.
Got it? Good. Because the management assumes that you already know this after you place your order.
