I love how Jack, even when clearly tilted and not happy with what's happened to his food due to lowered quality that he actually recognizes, refuses to give a restaurant a failing grade.
Imagine being sofa king wee todd edd that you refuse to grade a place poorly because you delusionally think it makes you look bad because you chose to go there. Sheeit, by this logic I should've loved the soul food place I once went to since despite their food being the driest shit humanly out there because they had a killer home made series of sauces to apply for their chicken. Also because it'd make me somehow look bad if I said that soul food place was bad.
It takes exceptional narcissism to pull something like that off.
