MSRP: Money Short? Reconsider Purchase

I worked at Abercrombie and Fitch a few years ago. I was on the register, ringing a lady up:

Me: “Your total is [almost $100].”

She hands me a $50 bill. After realizing she wasn’t planning on adding more money to it:

Me: “That’s not enough.”

Customer: “That’s all I can do, take it or leave it.”

Me: “Ma’am, this is an Abercrombie & Fitch, not a yard sale. If my choices are take it or leave it, you’re not getting a gold star for correctly guessing which of those two I’m going with…”

She did not like my choice.
