does it say you CANNOT? I don't understand people who ask if you can do something. They specifically prohibit coupons and drinks. If they want to exclude rewards or gift cards...they will tell you that. Otherwise it's good to go if it doesn't tell you not to in the guidelines.
If you that worried about it...scan/enter the code from a different receipt for your points instead of your own. I'm sure there are plenty of receipts that are not being used by customers.
