Alissa,
There are tons of couponers out there that feel the same way that you do. I think it's more because of the fact that more people are attempting coupon fraud now. I've heard stories of managers getting wrote up for accepting a bad coupon and as a result, the store cracks down more.
Personally I don't have a problem with anyone looking hard at my coupons...as long as they take them, I'm happy!
