The idea is to give restaurant servers (or really anyone who works for tips) a simple, no-nonsense tool to track income & expenses and see their daily spending budget.
This could be disastrous, but if you want to login and look around, you can use username 'employee' with pw 'applesaucegingersnaps'. I guess we'll see what happens if multiple people are logged in making edits at the same time!
When I was server, this is something I would've liked to have had. I haven't done much market probing yet, but any critique is welcomed and encouraged, per usual Show HN!
