I’ve now heard of so many people doing this since COVID, I had never even known this was a thing lol. I would think the popcorn would be cold by the time you get it home and to me there’s little worse than cold popcorn. But that could also be because for me the closest theater is a 30 minute drive with tons of traffic and lights. Even when I lived on Long Island, the closest theater was a good 20+ minutes away. But, if I had a closer theater I could totally see doing this, if I could get it home warm!
