Every Christmas I take 4-5 cases of beer to the kitchen staff. Nothing expensive I have found the most of these guys drink PBR when they are off. I will throw some bud, coors and even some corona in the mix. I love to see their faces when they realize people do appreciate the work they do. I have 4-5 place I do this every year and found that they will alway go the extra length for people and employees that I send there.
I don't make a big deal out of it, I just tell TWO people that the beer is for cooks and have a great Christmas.
If you have a regular place maybe you will want to "pay it forward" You won't regret it.
