A Regular For The Regular

(I am in the middle of a very long shift on a busy weekend. I see a regular customer approach and greet her.)

Me: “Hello, ma’am! What can I get for you?”

Customer: “I want a [drink], please, regular size.”

Me: “Okay, but what size did you want exactly? We have the medium and the small size.”

(I only ask this because many people say regular for both medium and small, and I want to get her order right.)

Customer: *stares at me* “I want a regular size.”

Me: “Okay, but when some people say regular, they could mean either of the two sizes.”

Customer: *still refuses to say a certain size and points at the medium cup, talking to me in a teaching and demeaning tone* “When people say regular, it’s always this size cup, okay?”

Me: “Okay.”

(I took her order and quickly made her drinks to get her out as quickly as possible. That, to be honest, prevented me from being cheery and light to the other customers. Just so you know, ma’am, several months ago our medium size was called a large, and our small cups were called a regular. Older customers get confused by the cup size change to this day. I’m sorry that you had to teach me about our own names for cups for trying to make sure I got the right size you wanted.)
