Only in the %Towns will you find a MO girl who is the mashgiach at an eatery. Does that happen in Teaneck too?!?
Yes. In Teaneck you have Modern Orthodox kids as mashgichim, waiters or cashiers trusted as the designated shomer shabbos.
The Mehadrin hashgacha is a good hechsher. It’s run by top notch poskim. They didn’t weaken any standards.
