Hello there! I'm trying to recall a video I watched about British expressions around a year ago. In the video, they explained the meaning of 'cheeky coffee' and also mentioned another expression with a similar meaning, but I can't remember it. If I remember correctly, it sounded like 'to have a coffee on a...', with the meaning 'to have a coffee quickly between two tasks/on the way'. Do you know what the word could be in place of the dots? Thank you!
