You're*

You probably got the checker in trouble. Good job asshole.

If you're going to be this put out over people using a line correctly, go somewhere that has express lanes. No adult should be this whiney.

such a glorious sense of entitlement! you must be very special.

Since when is it a requirement to let someone with just a few items go in front of you in line? Yes, this is a nice thing to do, but it's definitely not required. Take a Xanax and chill out. Maybe even do some nice things for others to counteract the terrible karma you earned being so mean.

Nobody owes you shit.
