I don't understand why. If one works with customers there are two possibilities. One, their company has strict protocols that keeps them safe and so they should still be worried about getting it from guests. Two, their company is lax on protocols and so they are the ones risking the lives of their guests. Either way, I am surprised to see this comment on HN, I would expect people here to not look at it at the individual level, and think in terms of probabilities.
