Are you obligated to say "yes" if someone asks to cut in line?
It's 6:00 PM at the grocery store, only 1 cashier, the line to get rung up is incredibly long, my 2 year old is sitting in the cart and I'm trying to keep him entertained so he doesn't run around the store. I just finished unloading about $100 worth of groceries on the automatic loading thing when the guy behind me asks if he can cut in front of me. I had been waiting in line for about 10 minutes with melting ice cream, frozen food, etc. etc.
I look at the guy (who's wearing sunglasses...inside the store), raise one eyebrow, point to the self-checkout lanes, and ask him why he didn't just go to the self-checkout, and his answer was that the lines were too long there, too.
Before I post my answer of what I did, I ask my fellow wooters, "Are you obligated to say 'yes' if someone asks to cut in line?"
