[Rick and Morty] Why, in Mortynight Run, does Rick says "Hold on to this. [...] If you lose it won't be able to get [your dad] back" when later it's shown that Jerry can leave at any time?

The ticket works like a coat check, or a valet parking ticket.  If Morty shows up without it, the clerk won't be able to tell which Jerry originally arrived with Morty.  He might get \*a\* Jerry back, but it wouldn't likely be his Dad.

Also, the clerk is *supposed* to stop people from claiming other people's Jerrys, but let's be honest: That dude is not paid enough to try and fight Rick & Morty if they decide to press the issue.  He knows damn well that's a good way to get your organs emancipated.
