She was probably a secret shopper.🙄

I don't kiss ass. I don't kiss my superior's ass and I damned sure don't kiss customer ass. I will be polite and professional, and if that's not enough for you, fuck off.

I went off on a customer only once because she was pushing and pushing and actually snapped her fingers in my face like I was a dog. I threw her ass out of the store then closed for the rest of the day. The company said I had to go to anger management or be fired. 😂 I did the anger management. But I left that job less than a year later because I found something else I liked better.

Sometimes waiters and waitress don't have their justice. The owner usually leans on the customer's side. 😕

I'm on your side

Until it is a secret shopper, which is exactly what she sounds like 😮

Haven't you heard the expression " The customer is always right"?
You were definitely in the wrong here

People are jerks. Dont worry about it. It sounds as if you were polite for the most part. You didnt curse so she doesnt have a complaint.

You are overthinking it. The worst that might happen is retraining in proper protocol...
