No, Just people with an excessive amount of coupons annoy me.
And you know what, it's not even the AMOUNT of coupons someone has, It's that fact that they want you to go REALLY slow and scan each coupon one-by-one to make sure you "got every one" and that it is "taking off the right amount"
Like no, Could you please let me do my job, once I give you the receipt you can check over it, and if something is wrong WE CAN FIX IT. But don't make me hold up my growing line because you want 25% all your t-shirts.
