We noticed DD on Ave P between McDonald and East 2nd was using the very same “Cholov Yisroel” milk container ( for those who asked for it ) with the same exp date every day for a long time, for a long time after the exp date, somehow the same bottle was always full and it never spoiled…mamesh a miracle
Also another “kosher” DD was caught putting an employee’s Bacon in the same microwave they used for customers …….that’s when they lost the chof k
In short I would not eat from DD even with a hechsher….unless a yid owns and runs it (which I don’t think is the case in any ) and a good hashgocha
If they are willing to save a dollar by keep on refilling the same empty cholov yisoel milk container with cholov stam milk, and serve cholov stam milk to customers who clearly think they are getting CY milk, I wonder what else are they willing to save a buck or more on when no one is looking
