I don't think that the city should be able to impose this arduous constraint on private businesses. These businesses have already suffered greatly under the capacity restrictions of closures. Now they're being asked to turn away potential customers and enforce unpopular rules without compensation, under threat of substantial penalties.
If the city wants to impose this rule, then at the very least they should handle the enforcement. Outsourcing the mandate without compensation is absurd.
Currently it’s actually the opposite in that the best restaurants are thriving because they ~doubled capacity by adding huge outdoor dining structures on the sidewalks that were previously not allowed. Note that it only impacts indoor dining not outdoor and that some restaurants, gyms, and venues has already begun to require of their own volition.
