I have never bought a popcorn bucket in my entire life... but I think the Tram one will force me to
As far as the "get off the tram" part, back in the day when there was a tram stop, people were just allowed to stay in the stop point as long as they wanted, and just boarded another tram whenever they wanted. Of course, guides had to emphasize a lot that you had to take everything with you, as you wouldn't be continuing on the same tram. Not sure if they'll do it that way this time, but it's precedent.
