I shower morning & night, and wash my hands for dinner (and after catching public transport).
Snacks don't warrant clean hands
I can however see where this comes in handy, around the technologically incompetent, like my Gf.
I had to ban her from my Computer Room, after she took a wet, soapy rag to my monitors & PC's, while they were operating, ... to clean the dust off :eek::eek::eek:
She's the sort of person that WOULD put a keyboard though a dishwasher.
