I do. If drinking scotch, for an Islay malt, I'll ask for a water back typically to add a few drops to the glass. I'm particularly fond of Speysides and Highland malts, but every now and then nothing goes so well as a bracing Islay. If we're talking bourbon or Irish whiskey, always neat.
Edit: Sorry, missed the second part. I've never actually had a bartender not understand my request for a neat pour.
