Even when you order from JustEat, don’t you give the delivery driver a number to call when they arrive (or get lost)? They almost never come directly to my apartment or office; I usually get a call saying they’re downstairs or outside (if parking is bad) instead.

In...olden times when people ordered by talking to other people, you’d often pay cash. Some places would take credit cards, usually by reading the number out loud. One fancy place let you type the numbers in with the touch pad.
