A Tale of Two Burger Joints
You wait in line so the cashier can take your order. There’s about 4 guests ahead of you, and an ever increasing line of people behind you. Once you place your order, they give you a pager that lights up and vibrates when your food is ready. You step off the line and wait with the other people who placed their order before you. Eventually your buzzer goes off, you take your tray of deliciousness from the counter, and squeeze past the lines of people waiting to find a table. This whole process takes about 20-30 minutes.
There are about 3 people in ahead of you in line. The cashier takes the order of the person in front. Then, after about 15 minutes, the customer’s food is ready and they take it and leave. Now there are only 2 people in front of you in line, and the same process happens: no other orders can be taken until the transaction is complete. You have to wait until everyone in front of you places their order, pays, and gets their food. The whole process takes a really long time.
You may be thinking that Restaurant #1 sounds like any fast food place, and that you would never see a place like Restaurant #2 in business.
