This is the place to post questions and discussions on usage and style. The members of the Wordwizard Clubhouse will also often be able to help you to formulate that difficult letter.
What word do you use to call a customer who has been buying drinks or food or staying at a restaurant, a pub, a shop or a hotel for almost 20 years?
Your answers will be greatly appreciated.
You could call them a regular, a regular customer / patron, (more rarely) an habitué or (jocularly) a frequent flyer.
They could also be described as a familiar face, frequenter or even haunter.
If I were the owner of the pub/shop/restaurant, I would call them "Sir" or "Madam"...
