I am going to go on a rant.
Yesterday I served a Coupon Queen who FLIPPED THE smurf OUT because she misplaced a coupon in her giant folder. And by flipped the smurf out what I mean is she looked at me with the panic-stricken sneer and said "I HAVE LOST A COUPON," picked up all her belongings and said "You'll have to hold my things, I must find this coupon. I must find it."
Afterwards her coupons weren't doubling because they didn't meet the specific requirements of the doubling deal and she, again, flips the smurf out. "Ma'am I can read, it's UP TO $2.00. We double coupons UP TO $2.00. We don't double coupons for $2.50." Eventually we just gave it to her because she just kept getting more and more upset. She ended up paying $2.67 for like 40 bucks worth of stuff and kept asking me if I thought she was a good shopper because she was able to do that, don't you think I planned well, didn't I do a good job.
I am a fan of a legitimate bargain as much as anybody but don't push what you're not owed, freaking coupon queens!
