i dont believe you...........we are perfectly entitled to work (alone) as long as we keep our distance from customers and follow a few basic hygiene rules and common sense(like refusing tea/coffee,insisting on cashless payments,etc)....
the risk is very small.........
But still a risk!
I crossed a couple of roads this evening even though 456 pedestrian deaths in the UK in 2018 were pedestrians. I also drove a car this morning even though there were nearly 2000 deaths from road traffic accidents (not sure if that includes the drivers who killed 456 pedestrians).
If you want to further minimise the risk of dying or killing someone, never cross a road and never drive a vehicle.
However, given that we're a population of 67 million, the risk of you killing someone while driving, or being killed, is still extremely low.
Context is everything.
