Why do you think Chabad provided popcorn? And what does that even mean, that they make it in their home and bring it to the hotel to hand out for free?
pcorn?
family members who were there told me they did.
My family wouldn't eat the non-kosher popcorn but maybe there were people there who would and Chabad did it to save people from eating non-kosher popcorn?
Do they cook all the restaurant food in their home and then bring it to the hotel? Maybe they decided to supervise the hotel making it in the kosher kitchen.
