Walmart madness

I was in Walmart with my 1 year old and 5 year old today, and my 1 year old started to get cranky when we were waiting in the checkout line (it was the checkout line by the garden area) so as we are waiting, my 1 year screaming, my 5 year old running around the cart, and I’m still keeping my cool, but then right before the cashier was about to call us next because we were next in line, a women just goes in front and gives her stuff to the cashier to ring her up. Now usually I would have let it go but my son brought up how come in school they tell him that’s not right but I let her so, I went up to the cashier with my cart, and told her, “Sorry, but there was a long line right behind you and you have to wait your turn,” and instead of apologizing she just says, “well I didn’t see it, they should have a sign showing where the line is,” which the line was not hard to see and she did see it because while she was waiting for the women in front of me she looked at the line and just shrugged her shoulders like if she was better then the rest of us and didn’t have to wait, I just told her, “clearly anyone with the right head on their shoulders, and who is not childish would have seen the line,” she just left. Then the cashier told me, “good for you, I’m tired of people thinking they better then everyone else, and she didn’t even apologize,” and I just said “some people just don’t have manners, and I have to show my kids right from wrong.”
