Shop-floor rules
Do
Don't
Stamp when they arrive. End-of-class stamping creates a second queue.
The guest does not need their own card. Redeem the member’s full card, then train.
Keep Stampzo for the loyalty loop. Don’t mix it with paid session packs on the same card.
First program is free. Most shops are scanning the same afternoon.
