I seem to remember "No shirt, no shoes, no service" in my time, justified as a public health measure (even if that wasn't the real justification). Likewise food service workers have long been required to bandage wounds, wear hair nets and gloves, avoid work when ill, etc. If COVID were only transmissible when you were symptomatic there would probably be no real public health need to apply this kind of check. But since it is silly to think you can simultaneously use masks and eat in a restaurant, as anti-vaxxers are fond of reminding us, you're left with measures like that if you want indoor dining in a restaurant.
