seriously?

Well today is the last day to double coupons at Albertsons...so knowing they would be in short supply i didn't go in with high expectations but what happened next was so annoying...!
since we are in the middle of a move i don't want to buy food that i will have to haul around for the next two weeks but i found an amazing deal on toilet paper....15 cents a pack...who can resist that? so i break down and went shopping. i go and and they are out of the specific pack that i need to use my coupon...so like in Boise you can grab the closest price to it and they will lower the price and let you use your coupon(albertsons policy is to have the shelves stocked at all time) well i get up to the register with my six packages of toilet paper and they ring up at 5 dollars...well then i say your out...the ones i wanted were 2.15. she says snotty "I cant do that..." after telling her albertsons policy she gets frustrated and says well if you don't want to pay full price go someplace else....HOW RUDE IS THAT?!
She is VERY lucky i was angry and didn't have the patients to talk to her manager! need less to say i didn't get my 15 cent toilet paper...
