20% are sick and can't work. Then a good chunk of other 80% are not needed because a good chunk of customers are gone. Then quite a bit of people are scared of getting virus, ain't in the mood because of their relatives dying and/or economic situation and don't consume. Demand goes even lower. More people loose their jobs and demand goes even lower. And the spiral continues. Bars and restaurants are great for spreading the virus. Once people learn it the hard way, remaining people won't go there that much. In my country patronising of bars and restaurants fell down the cliff in a couple days mid-march. Closing them down due to quarantine was just a formality in many cases. Sure, some people would still go. But they wouldn't have enough traffic to cover fixed costs.
