I like to show you my app, called "Beer Tapper",
published in googlePlayStore and here at AndroidPit.
Discription:
"Help the tappers in the operation of its guests. Watch out that no beer mugs shatter or fall on the wall. Make sure that the guests do not have to wait too long, otherwise they will be grumpy.
So, have fun"
