I wanted a small coffee in a medium cup .I was refused .so l left never to return. Small coffee sloshes in the car making a mess. Small coffee in a medium cup works fine .so I will frequent the shops that will accommodate my needs

They want you to pay for the medium cup but you get a small they probably just didn't know how to say that

I don't shop there much.

They have bad customer service

I hear what you are saying, so yes go somewhere where they will accommodate you.

They don't know how to run a business there
