You know who waiters and waitresses hate? Groups of people who give them 8 different credit cards and a set of rules to split a tab. Stop being a person in that group. Simply give the You Pay Bottle Opener a spin, and one unlucky soul will get stuck with the bill. No more messing around with who had what and how the tip will work. And when it’s not helping you make quick and brutal decisions, it can pop a few bottles for you to celebrate the free meal you just had. Hopefully.
