20. Multiple Times
Back in high school, I discovered that if you call any “Questions/Comments” number on a food product, you could make up literally anything and get a coupon for a free whatever it was. So, for instance, we’d call Bisquick pancake mix and say we bought a jar of the mix but inside we found three already-made pancakes… sh*t like that, just nonsensical stuff. We did it so much that we’d pile up the coupons, go to the grocery store and check out a full cart of groceries and just hand the cashier a stack of these coupons and not pay a cent for hundreds of dollars worth of groceries. We did that multiple times, and eventually, the big companies (Kraft, General Mills, etc) catch on and you have to use different names and addresses. I’ll never forget the exasperation of the poor person on the other end of the line when I told them the chicken patties I bought just get more frozen every time I put them in the microwave.
