Someone's stirring up the Bees Nest about "you" doing the work at Self-checkouts

I shop once a month and with prices the way they are now I'm spending over 400 bucks at Walmart, with a cart filled to the brim, I was in line, no one behind me and the checkout girl with a really shitty attitude said why didn't you go to the self-checkout, I said I'd feel better if you did it and she grunted like I was making her do her job, she just had a piiss poor attitude I let her get halve way through and said you need a different job and walked out. I went to the small Food Lion a little down the road that's been there forever, all was good, no more Walmart.
They all have an attitude. one these days I'm going reach over the counter and grab that pencil neck , nose ring wearing, disrespectful peace of **** and teach him a lesson his daddy or mommy never taught him. We order online pickup when I go with the wife, no extra charge and no attitude.
