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.
