#1 IF YOU MAKE A MESS, CLEAN IT UP
Put your trash in the wastebasket, wipe up spills and crumbs.
#2 THE REFRIGERATOR IS FOR TEMPORARY STORAGE
Put your meal or snack there until you eat it, but don't forget about it... no one likes to see moldy food in the fridge!
#3 PUT A LABEL ON IT
Protect your food in the fridge by putting you name on it. If you bring a dish to share, use a label to let people know it's cool to dig in.
#4 KILL IT? REFILL IT
If you finish the coffee, make a fresh pot. If you use the last of anything, replace it... paper towels, napkins, creamer, sugar... be sure there's some for the next person.
#5 DON'T DITCH YOUR DIRTY DISHES
Wash them and put them away immediately after use.
#6 BE MINDFUL OF OTHERS.
You don't like it when your food gets mashed in the fridge or if someone cooks or opens a smelly dish. Your co-workers don't like it either. Think before you eat.
