No one pre-pays at the Chipotles in Orlando. You order the ingredients for your meal as you work your way down the line to the register. Maybe it’s a regional thing. I know in NYC you hit the register first. If the guys were known to order food first and not have the money to pay at the register, the manager was perfectly justified in asking that they pay first.
This one’s pretty cut and dried when you take into consideration that not all Chipotles operate the same way.
