Dangerous things are either banned, or regulated. This includes operating deadly equipment (drivers licenses) and it includes dress codes in pubic (sanitation is important!). Notably most places only request customers wash their hands but require employees to. That is a distinction made because of the extremely high risk of improper sanitation during food prep versus consumption. Restaurants, including fast food, __should__ be cleaning tables and other common surfaces between uses or at least very frequently to minimize risk.
My position includes enforcement of "herd immunity" (vaccination to the greatest extent possible) as a requirement for participating in society, and then narrowly allows exceptions only where it would not be effective / be greatly riskier for the personal health of the individual than the prevention (thus including the person in the narrow class most protected by the immunity among _others_ rather than a personal contribution to that shared social immunity), OR for those who shun all medical care entirely as a wholistic religious exemption of entirely opting out of that social sector and responsibility as well.
Limiting to only those two classes, plus those for whom the vaccines are not authorized, should hopefully still retain a sufficient group resistance to cause outbreaks to fizzle out, rather than flare up and spread.
Please take the time to read my entire premise (initial reply) and make an attempt to understand the full logic before commenting on it.
