Cup of Joe
My Dad is a recycling man for my town. And man did he ever do this well. So with Mcdonald’s, you know how you can get a stamp card and a sticker on every cup? When you fill out the stamp card you get a free drink. Well whenever he goes to pick up someone’s recycling, sometimes a person leaves their Mcdonald’s drink cup in there. And the sticker is still on it.
So he takes the sticker and puts it on his stamp card. Let’s say he has over 50+ stamp cards for a free drink by doing this, and counting. He is exploiting that one for sure. Free coffee for life.
