Many things have changed during the pandemic. Downtown there are signs in the elevators advising people to take separate elevators for social distancing unless they are from the same household.
There isn’t a way to social distance in an elevator. Last week while I was in an elevator going down a group of people who wanted to go up got in the elevator with me. It was a group of people who were headed to a party. They all had masks on but I am sure they don’t have a clue about the whole elevator thing.
If you need to take an elevator don’t get in it if there is already someone in it. Yes, one person per elevator does mean longer wait times for elevators and it may also save lives.
