i dont' think anyone that doesn't offer is rude - i just do it as a matter of course. my guests probably get sick of me offering drinks. i always have water with me, so i guess i make an extra effort to make sure everyone is taken care of

i don't think many tradies (my brother excluded lol) have accepted, but particularly in hot weather, i make sure i offer a drink. i know they often have drinks in the ute/truck, but i take on the thought that, no matter how good a cooler they have, unless they pack everything in ice every day, it's not the same as having an icy one from the fridge
