Well, if my goal in life was to p*** off some poor old lady working as a cashier at the grocery store, I guess I can die happy now... Ugh, what a mountain from a mole hill... I literally had around 30-40 coupons, the majority of which were manufacturers coupons. As she starts manually checking I had the right items and keying in the dollar amounts for the discounts, I commented, trying to be sympathetic, "Oh, jeez- you can't just scan the bar code?" So she gives it a try, and no dice. Anyway, near the end of the coupons, she tosses one off to the side. I asked about it, and she said she didn't think I could use that one, but she would check at the end. Ok, cool. At the end she scans it, and says, "See? It says its invalid. You already used one of those. You can try to use it somewhere else if you want." Ok, I get that I already made your list of least favorite people in the store when I walked up with my fistful of coupons, but I wasn't born yesterday. I nicely pointed out that one coupon says it excludes campbell's "great for cooking" soups, and this one was specifically for the "great for cooking" soups. Similar, but not the same. Also, I already had the soup rung in, and now buried at the bottom of the shopping cart. She starts keying it in and says, "Fine, I could lose my job over this. For a dollar. Is that what you want? For me to lose my job over a dollar? Does that make you happy?" I calmly responded, "You are more than welcome to call the manager over if you'd like." That was the end of it, but come on- I just watched you try to scan a coupon and it didn't work and then you try to use that to convince me a manufacturers coupon isn't valid when you have been keying in the dollar amounts the WHOLE time?? Then she complained about me to the next two people in line while I was bagging my groceries. How awkward. I feel bad for ruining her day, but I could have said "it's just a dollar" to every one of those coupons, and I would have paid $168 instead of $106. ::humph::
