Pay full price forever

I overheard this interaction today and i think it will haunt me forever.

A guest comes in and wants to purchase an item. My coworker was helping, but I was right behind her. The customer is asking if we have any "buy more, save more" deals so my coworker says "if you buy a case of 12 or more you get a discount."

The woman scoffs at her to her face and says, "I've been shopping here for years. I'm a repeat customer and I spend so much money here. I have an e-mail account you should know me." My coworker plugs her email in the system and she's not entitled to any discounts.

She finishes paying and goes, "well what did I get off then? Don't you have a loyalty program I should have saved something"

My coworker just tells her she paid regular price. You only get a discount for buying 12 or more.

The woman sputters out, "So I have to pay full price.... On everything..... Forever????"

I had to remove myself from the area because i almost started laughing. Yes, forever!!!

When she left we looked at her profile and she had been there 1 time before in 2020 and bought one thing LMAO. Ma'am!!!!!!!!!!!!
