I think you will find many SCers just avoid SC like the plague lol

I just got home from a grocery store that was refusing to take a coupon from a coupon book that I found IN THEIR STORE!! I have told them that the past 4 weeks in a row!! This time I talked to the store manager and owner. Its embarrassing!! I use coupons all of the time and find that cashiers are getting more miserable about it. You try and save money and get a hard time about it.
