To respond to Hans’s post: in order for the government to force Geno’s to serve everyone who stumbles up to the window indiscriminately, it would have to deny private businesses’ right to refuse service.

As far as I know, a business can reserve the right to refuse service for almost any reason, whether it’s the clothes they wear, their age, or the language they speak–whether English or another language (and one may question whether the language the workers at Geno’s speaks is actually English).
