In Japan, many small restaurants allow customers to order their food from a vending machine. Put in your money and out pops a ticket for what you want. Then just take your place and the waitress will bring your water and take your ticket to the kitchen. In a few minutes, she'll return for your food.

A great way to prevent employee theft at the register as well as minimize record keeping and the number of staff you need to operate a business.
