Who are you trying to kid?

I thoroughly enjoy using the "self-checkout" aisle in pretty much any store. I enjoy the control. I swipe things in the order I want, I fill the bags correctly (bread on the TOP, thank you), and I can go as fast or slow as I want.

The Jewel at Grand & State is right by the train station so I go there a lot- yogurts and juice a couple of times a week for breakfasts at work, andalso veryconvenient for grabbing something on the way home from work for dinner.

I did both today- I was out of yogurt so I grabbed some on the way in, and I swung by after work because I was jonesing for mac n' cheese (sue me).

Both times, I got in the (very short) line by the self checkout aisles.
BOTH TIMES, someone just wandered in front of me ,camein from theside and attempted to go to the next open spot.
Both times, I said "exscuse me- the LINE is right here"
Both times, they said "what?"
Both times I repeat,"The LINE is RIGHT HERE"
Both times, I get the stink eye.

My point?
Who goes into the supermarket and just expects there to be no line for something?
I mean, what planet are you from?

(And before you ask, YES, I always point out when someone cuts in line. I'm an asshole like that.)
