I was going to give this Dutch Brothers 5 stars but after my two past experiences I will say I'm very disappointed. I guess I don't understand the point of a stamp card if they won't stamp it. The last two times I've purchased two drinks expecting a stamp for each visit or even two stamps for purchasing each drink. The same man who has been serving the drinks through the drive thru will act as if he's stamping the card and will talk to you so you don't look down and see he didn't actually stamp it... it's actually frustrating when you give them a tip and get nothing in return. I will sadly not be returning and will go out of my way to go to the Dutch Brothers off Bell Rd to get better customer service.
