Just found out from a former McDonalds employee that you should always ask for a receipt when you order!

A former McDonald’s worker says asking for a receipt could make employees more careful with your order. Since mystery shoppers often request receipts to evaluate service, staff may become more attentive, double-checking food quality and accuracy.

It’s not guaranteed, but this simple habit can lead to better service—and it also gives you proof of purchase if there’s a mistake.
