Here is a list of things about which OH and disagree as to whether they should be kept in the fridge. Ours is an Anglo-American relationship, but I don't think all these differences of opinion are down to that....
Eggs
Ketchup and HP
Mayo - not fresh made. PseudoHellmans
Grapes and other casual pick-one-up fruit
Onions
*White wine you don't plan to drink soon
Opened jam and marmalade
Tomatoes
Butter in winter
Pickles and capers in jars
Easy garlic and tomato puree in tubes
*Possible red herring, as we never have white wine that we're not planning to drink soon,
