restaurant service tip

They do this awesome thing at Bubba Gumps where there's a clear sign on each table that either says "Run Forrest Run" or "Stop Forrest Stop." And depending on how you've flipped the sign, a waitstaff will come to your table even if it's not the person who took your order. Why the heck aren't more restaurants doing this?! Instead, I swear they come by when you're mouth is full and ask, "Is everything OK this evening?"
