At the first sight this sounds like a very simple problem. Give away 2-3 sets for free to your favorite places (even for a few months, if you can't afford giving away as a gift), and as an exchange only ask for feedback (from the perspective of a target user) and gather KPI numbers. Win for everyone.

(Of course don't forget to record the initial state before your gadget, whatever that is: drink/person, tip spent/hour, etc... so you can show a before/after state to your prospects)
