Cashier: (sets my sandwich to go)
Me: "Just the sandwich today" (I said while holding my cash)
Cashier: "Would you like chips & a drink?"
Me: "No, just the sandwich"
Cashier: (rings up my order)
Me: (shocked look on my face as it was more than I thought)
Cashier: "That is the total with chips & a drink"
Me: "I wanted just the sandwich."
Cashier: (refigures the order) and says, "Have a nice day".
