DeLeon isn’t sure the handshake is ever coming back. The stickers his company sold were never hot sellers. Other companies hawked signs and stickers that more firmly discouraged handshaking — including one featuring a skeleton hand and another covered with COVID-19 germs.

“I played golf with a guy the other day, who I had never met and we got along really well. And on the 18th green it is traditional that you stick your hand out and you take your hat off and you shake hands with who you played with,” he said. “And we just kind of stared at each other and fist-bumped and walked off.”

Not so fast, say etiquette experts and businesspeople like Dave McClain, 52, of Overland Park, Kansas. McClain recalls coming across one of the “I Shake Hands” stickers at a networking event and slapping it onto his shirt.

“You can make phone calls all you want and you can meet with people online via Zoom call but it is just not the same as being able to reach out your hand and shake their hand, look them in the eye and really establish that rapport,” he said.
