Not Even In Line And Out Of Line, Part 7

I’m working at the checkout in a grocery store. It’s admittedly very busy and chaotic, but most customers are forming orderly lines at the checkouts. A customer cuts through a bunch of customers and stands ready for me to serve him next.

Me: “Sir, there is a line.”

Customer: “I’ve made a new line.”

Me: “Uh, no, sir, there’s only one line.”

Customer: “Show me where it says there can only be one line.”

Me: “Well… it doesn’t, but it’s generally understood—”

Customer: “So, there’s no sign saying I can’t do it? Well then, here I am. Serve me next.” 

I look over to the other three customers in line, all glaring at this guy. I start speaking to them all.

Me: “If you could all move two inches to the left to make an even newer line, I can serve you first!”

The glaring customers immediately smile and move an inch or so to the left — but still very much in the same line — and I serve them next.

Customer: “What are you doing? I was next in line!”

Me: “I made a new line.”

Customer: “But I made the new line! I was next!”

Me: “Show me where it says there can only be one ‘new’ line.”

The customer glared at me, threw his items to the ground in protest, and stormed out.
