If you are saying that working on the front lines is difficult because of all of the filthy coughers then I say you’re right, thank you and goodluck. Or if your saying that there are 30 yro covid spreaders infiltrating your front line bus route then I’m game for more reports in the future.
I would say a 30 year old infiltrator. I am always leery of people with no luggage from the airport. If they have no luggage, they are usually getting a ride because they returned a rental car from the rental car center.
