Baskin-robbins

Gave the man a perfectly valid coupon for a milkshake... He stood there in front of me said there was no barcode and sarcastically looked me in the face and scanned a non existant barcode and laughed... I paid full price for my milkshake, got my receipt and suprise suprise got another coupon with no barcode. Both were valid and he honored nothing. Your lack of understanding on how to use your own POS should not subject me to you sarcasm or take my dollar. To be fair I was already having a bad day and I paid full price for a runny milkshake...
