I once tried to eat half the average daily mayonnaise intake of an average Midwesterner. Had to stop after 4 days and got so sick I called my doctor. Now I order no mayo on food, but restaurant workers try to burn me as an inhuman heretic. Subway here serves mayonnaise eclairs.
If that’s where you bite into a sandwich and it squirts a stream of mayonnaise, and you open the sandwich and there’s a core of mayo running the entire length and dripping from every edge, yes I have. That’s every sandwich up here unless you go full heretic and order none.
