thank you-daas yochid- this is exactly what i meant ! You are always “on the money’ in all issues that you are discussing.
By the way- on a personal level, I have never seen any “treif’ sandwiches in a starbucks. Maybe chicago is different. In any case, there would be a million “tsedoddim lehetter” not least the fact that the vast majority of utensils are washed with soap (I can’t even imagine not using soap)that gives it the “nossen taam lifgam”.
