I prefer people to ask for a 'crosshead' screwdriver, so that I have an intro for asking whether they want Pozi and Phillips so that I can give them the right one. If they come asking for one or the other, it's a bit presumptious to suggest they might be wrong and grill them over what kind of recess their screw has. I usually say something like 'Please only use it for Phillips screws, if you need a Pozidriv too, you're welcome to take that as well.'
'Actually, I think you need a JIS' usually draws odd looks. I keep and use them regularly as I often work on Japanese equipment.
