Can't see one privately owned coffee shop giving out free cups for rewards points earnt at another. For them kind of defeats the purpose of it being a loyalty system for them. Would work fine for big coffee chains like Gloria Jeans though. I had also read that a preordering system was part of the offering to so they have that base covered. That could work really well for someone doing a coffee run for work mates where big orders are involved.
