ketchup... out, if you disagree just remember that diners don't refrigerate the bottles.
Maple syrup.... I agree, the fridge... but if you buy the nifty short bottle once you can microwave to taste.
Milk... a separate fridge kept barely above freezing, not for safety, just because it tastes better that way.
soy sauce.... soy sauce will out live us all, and probably our children no matter what the climate... it is the culinary equivalent of the Dead Sea.
Honey... I've heard that they actually found unspoiled honey in pyramids, so its probably safe in the cupboard.
