How tightly do they manage their production rate, presumably they're more careful than just "keep 6 on the warmer" and more like "the usual rate at this time is 70 per hour, we only lose 15% of those sales by asking the customer to wait, 5% of those losses go for other products, so we'll make at a rate of 1 every X minutes unless we have more than Y on hand"? (numbers completely off the top of my head) |

The sandwich wrappers had the numbers 1 to 12 printed on them, and you were supposed to mark the pre-made sandwiches to show when to throw them away. For example, if you assembled the sandwich at 12:15, mark the 5 to show that it should be thrown away when the clock's big hand is on the 5. Literacy not really required.
