at least the bagged ice is factory driven. I took a tour of a plant that makes the tube cubes. Clean, other than the constant thought of an amonia explosion... it was cool.
I used to clean a particular ice machine at a low ball strip joint. Every 2 months it would be thick with nicotine stains, yellow/brown sludge on the inside. It'd take me 2 hours to clear it out.
