Minimal stock sandwich makers

While travelling with my father in law we stopped for a late lunch at a pizza place in western New York. We both ordered a sub sandwich with different meats, but lettuce, tomato etc. Shortly afterwards, one of the people in the shop went out the door and, as we later discovered, down the mall to the Tops supermarket. Minutes later, she returned with a Tops shopping bag that had lettuce, tomato and onion in it, which was then used to make our sandwiches!

Admittedly, the sandwiches were tasty and the bread was nicely toasted in the pizza oven, but we thought it odd that they had to go out once the order was placed to get some of the sandwich fixings!!
