Free Specialty beverage after paying for 5

I buy 1-3 Frappes or smoothies 3x week. I have 4 punches on my "card". Since it takes hours for a purchase to show up, there is really no way to make sure you get credit for purchases. I often get an extra for my husband but I can only get a stamp on one. Also, I go through the drive thru as I am often too tired after a medical treatment to walk in and wait. I have to remember to give the cashier my iPhone before the money as I have been told many times "its too late". This is very frustrating! I like to think Im getting a reward for buying anything, but my reward is feeling more like a punishment. BK app lets me use multiple coupons and they serve some kind of iced coffee. Taco Bell serves a type of frozen drink. I may have to change my preferred cold pre and or post dialysis drink. Maybe if this was never offered, the opportunity to earn a free drink, I would be content. Since it is offered, I just feel irritated.
