HT SD final trip $0.37 OOP!!!!!!

OK so from going thru the wringer at PUblix with my bad cashier it goes to worse at HT at the U-scan line. 20 Minutes!!Asia was working and she was wicked!!!!! Basically my 2nd transaction i used 7 coupons and I was buying all items that, when the q's doubled, would be free. So when my total to pay came to $4-something I knew something was wrong so i went up to her stand to go over the q's and see what happened. And we scrolled thru my transaction and could only find 5 coupons scanned and doubled. SO I was like, "OK, well 2 of the q's didn't scan let's figure out which 2," and she was not having it. She was like, "I scanned all your coupons." And i was like, "well, you are holding 7 coupons but only 5 scanned, so somehow 2 didn't get scanned." and Asia was like, "I don't know because I scanned your coupons. You know, you just can't get stuff for free!" LOL yes, she said that to me. I was just in disbelief. So I say, "well, let's look at the coupons and your computer and figure out which ones didn't scan," and i proceeded to go down the short list of 5 coupons and eliminate each corresponding paper coupon by flipping it over. We were then left with 2 of the Playtex q's that were $1 q's and would have doubled to 0.99. So, basically there was the $4 discrepancey. And i was like, "see, these are the ones that didn't get scanned - scan these." And she stood there and argued and told me No, that she had scanned them already and i was like Am I in the Twilight Zone or what?? I told her that HT's registers are so precise with matching barcodes of items to the coupons that if she scanned a coupon for an item that was not purchased the register would not accept the coupon so, therefore, she had nothing to lose to scan the coupons for me. And she still said No!!!!!!!!!!!!!!!!!! I was like, OK, call the manager then because this is ridiculous. And at that point she scanned them, they doubled, and my new total was $0.36. She shook her dumb head in anger and had the nerve to say "That's not right, I already scanned them." ANd i was thinking "how can u possibly stand there and say that 5=7? because that was what she was saying - jsut nonsensical jibberish. I mean, i gave her 7 coupons and only 5 were on the transaction and to her that was a reality that made perfect sense. WOW. I paid my $0.36 and left. whatever, Asia!
