It's just bugging me that a café nearby has a loyalty card for hot drink purchases. The problem arose when I ordered and paid for two coffees, offered my loyalty card and was given just the one stamp. When I asked why it was only one stamp for two drinks, the reply was "it's one stamp per transaction"
The wording on the card states " buy 9 hot drinks and your 10th is free". AIBU expecting a stamp per drink and NOT per purchase? When I go in again, I will get DH his own card and we'll pay separately.
