DEAR MISS MANNERS: Is there a polite way to avoid shaking hands with strangers? I was in a car dealership, and every employee I encountered extended a hand to me, expecting me to shake it. I know that they were just trying to appear friendly and open. But I also know that this is a good way to transmit diseases and pathogenic microorganisms. Many people do not have good hand-washing practices, especially after using the restroom, and it grosses me out to have to touch their hands. An infectious-disease specialist has even stated that the practice of shaking hands should be abandoned.

If you can gracefully finesse another gesture — waving, or, in less formal situations, a fist bump — Miss Manners will allow it. Adding “I’m healthy, but don’t want you to risk it” will perhaps take away some of the sting.
