The threshold is where the customer wants it to be. If they don't satisfy my standards, I don't do business there. If I expect to see all the clerks and stockers in hazmat suits, and they're not, and I think it's just too goddamn dangerous to shop there, I won't. Is this odd to you? Do you not operate this way already? You eat at restaurants you don't like just because they're open? Maybe their advertising orders you to appear?
