This scenario might represent your friend's/family's general interactions with you and how they slight you by hiding behind good intentions...whenever you find yourself with them in an exciting/fun environment, it seems that they wish to appear like they're doing things to be good to you and make you happy, yet all of their actions are shallow and really meant for THEIR enjoyment, not yours. The toffee popcorn is also another indicator of their "sugar coated" intentions, and taking this popcorn from you further indicates how blatant their actions are to you and how intensely they affect you, yet they don't seem to notice that what they're doing is wrong at all....
A lot of assumptions on my part lol but worth a look, some may ring true for you...I certainly notice this kind of behavior with my family at times
