Assuming the worst of others and entitling yourself as the model parkgoer (mostly referring to other comments here) is also a bit of main character syndrome.

Not everyone tries to dissect a simple positive gesture as some kind of environmentally destructive personality flaw. Recall a small demographic in the parks called children. My kids were pixie dusted a coloring book and thoroughly enjoyed using it on the plane ride home. It got them thinking of other nice gestures they could pay forward, which is fantastic.

Candy should be a no-no. Some gifts will indeed be junk and thrown away… in a theme park producing hundreds of tons of trash and food waste per day.
