If you do leave a tip in Bitcoin at steak n shake, would the employee receive the dollar amount via paycheck? And , would that be a taxable event? What if they find out the tip I gave them in bitcoin hoes up in price more that if they take the dollar amount. It's something worth asking.

I think the gears will be turning in the employees minds. Stuff they haven't ever had to think about before. Maybe it's what they need to adopt btc.
