Thais don't cook at lot at home; it's generally cheaper to eat out than to cook in. We've heard that many Thai houses don't even have a kitchen. Our house does have a kitchen; in fact, the landlord knocked out a wall to make it even bigger. But many things in the kitchen are still smaller than we're used to. Case in point #1: the refrigerator.
Notice of the cabinets above the fridge; yeah, I've banged my 6'1" head on them more than once.
