to be clear, I'm not advocating eating in any of those.
cant you assume that they wont be adding anything else besides the mix they put in the machine? If i went to a carvel in idaho I believe we can assume that they didnt add anything to the ice cream with ou on it would be the same here.... better question is why wont the owner just get a hechsher on the whole store, I understand its expensive but im sure will bring a lot of business also.
