Oh man. I really hate shaking hands with most people.
At work when I go to the toilet and there are coworkers there too, I always make a mental note of who washes their hands after. If they don’t they go on the handshake/touch blacklist.
Some only wash their hands before 🤦.
Since COVID I always attempt to do a respectful bow.
I have no problem with shaking hands of close friends (who have good hygiene habits).
Good luck speaking when they are clogged up. :/
Maybe the nostrils should be redesigned too.
