Subway is the nation's largest fast-food chain, with over 21,110 locations as of spring 2019. Subway franchisees own and operate locations. However, Subway employees must follow some strange rules to keep a franchise open.
They must greet customers with the words: "Welcome to Subway"
Subway workers must give you as many veggies as you want
Sandwiches must be "made" with ingredients separated if asked for
Prepared meats must be microwaved, even for cold sandwiches
Managers are expected to act like spies when making bank deposits
Workers undergo five days of training and take multiple tests
