I've been working in the city since 2006 and it's happened to me at least 10 times or so. I've also offered tissues to people who were having a coughing fit (pre-covid) and once gave a woman who was really coughing an unopened bottle of water that I had. But that one was more of a group effort. About four of us were helping her in one way or another. I can't see that happening right now...I think the car would just clear out!
