Dr. Todd said “hotels run by frum but disorganized mashgichim, including some heimeshe hotels, cannot be trusted.”
Very true. I worked for a popular north jersey bakery many years ago, goyish owned with a mashgiach, and while they were quite careful about keeping kosher, the mashgiach was not kosher at all (ate cheeseburgers) and found it amusing. I was young and afraid to say anything though it bothers me now.
