Or you might be getting a few extra cents from them. It's being reported that Chipotle has started doing something strange with their bills: they're rounding bills to the nearest quarter. For example, a bill that should have been $35.24 was turned into $35.25.
The reason they're doing this is supposedly so that they can get people in and out of the store faster. It makes sense. Giving change in quarters is easier than going down to the individual cent. Chipotle says that the rounding basically takes money from some bills and gives it to others, so it's not Chipotle just taking pennies.
Still, the practice is illegal in certain areas if you don't tell people that's what you're doing. So in many markets, people have been protesting and Chipotle has added a 'rounding' line on customer's bills. Next time you're at a Chipotle (especially in New Jersey, where this practice was found), check the bill to see if they added or took some money from your bill.
