Why the low rating?

Im rating 5/5 only to make up for the horrible low rating this app has. I dont get what the problem is... Ive used this app many times, the McDonalds employees simply scan my coupon and bam, free 6 piece McNuggets with any purchase (when the local sports team wins a game), or free medium fries with any purchase on fridays. This app is awesome and saves you money if you like McDonalds.

Ive never had a problem with this app, even when at the airport McDonalds they still honor the coupons.
