“so dunkin donuts franchises now tell us whats kosher.”
There is nothing wrong with them advertising they have kosher supervision. You have picked the right forum for maximum lashon hara and rechilus with your rav hamachshir bashing.
“with no full time supervision and no yehudi at all working on the premises,”
Is there a din of donuts shenisalem min ha’ayin that we are not aware of?
As for the reports of outsiders coming in and heating things in the DD microwaves, even if the food was 1000% kosher beyond any shadow of a doubt, that is a gross violation of DD policy and should be reported to DD. If they are so sure of their information they should a)report it to the Rav hamachsir and b)report it to DD.
