On Yom Kippur, Karen Jimenez spent an hour arguing, as politely as possible, with a little old lady. Not because she wanted to, but because it was now part of her job as director of events at the New York City-based Prince George Ballroom.

The venue was hosting Yom Kippur services, and while the rabbi had communicated that proof of vaccinations were required to attend, this individual arrived without any documentation. “She was elderly so obviously we tried to accommodate her, but didn’t let her in,” Jimenez tells Fortune. “She was just like, I have CVS on the phone and I’m like, well that’s great, but unless CVS is FaceTiming me with your official paperwork…step to the side,” she adds with a laugh.

“That was not too crazy, but she definitely spent an hour on the steps, trying to get me to let her in. I can’t,” Jimenez recalls. “Funny enough, she actually did go to CVS to get a copy and she came back for later service.”

The return of weddings, concerts, and indoor events has created a new job: the COVID bouncer. Major cities including New York City, San Francisco, New Orleans, as well as Los Angeles county, require proof of vaccination to enter many indoor businesses, including bars, restaurants and event venues.
