Younger people love not having to wait in line. If I'm really hungry and I'm stopping at McDonald's because it's the only place close enough to the bus stop, then I want to order and pay, not wait for the person ahead of me. If I only have one item at the market/drug store, I want to use a self-checkout machine, and I don't want to be waiting behind someone with a cart full of items who doesn't know they have to actually unload their cart for the cashier, or who decides to go back for "one more thing" that happens to be at the back of the store where they get caught up talking to someone they know.
