@derechhamelech-(it is it’s im yirtzeh hashem by you)
Just because there is one place that sells subs doesn’t mean its the same thing. The bread they use for the subs is supposed to be very good along with the sauces, dressings etc. Some restaurants are better than others.
You are also falling into the trap of “the whole world is NYC.” All the subways mentioned aren’t in NYC. There is no Essex on Coney in these places.
@real-brisker-
Do you have a problem with the kosher lamp? It’s trying to be like the goyim and finding a “loophole” for something that’s assur, turning on a light. What about a blech? It’s finding a “loophole” to keep food warm on shabbos. There are no problems with “loopholes” in the torah. (Other than to put up safeguards and that isn’t a problem of being a “loophole”). Hashem knows what he wants to assur and he doesn’t need you saying “no I know that the Torah says that is mutar, but I know better”
