But making showing appreciation to the cooking staff really tangible and simple, makes showing appreciation easier. And that is where the six-pack of beer for the kitchen comes in. On top of tipping (which is customary in the USA anyway), buying a six-pack is a really easy way to show gratitude.
It makes people tip more often and makes the tipping amount higher. A win-win-win.
