The pizza delivery guy was awful
I was looking at the comments for this on reddit (I know, that was my first mistake) and they all misinterpret this guy the same way. Almost to a person they all think that the delivery guy's disgusted reaction was horror that he'd been 'enabling' Charlie the whole movie. WTF. Do these people have a working brain? He stayed to watch Charlie against his wishes and then makes this repulsed scoffing noise instead of even trying to save face, then runs off. I found him the cruelest and most inhuman character of the whole movie actually. At BEST he gave it no thought and just freaked out from awkwardness. At worst I actually think he was pretending to try to befriend Charlie in their previous interactions just to trick him into seeing him to assuage his curiosity. Who did he think was hiding behind the door, Brad Pitt? He knew what he was doing and it was such a cruelly thoughtless reaction.
My guess on why reddit kept reacting this way is that just want to think anyone ethnic in a movie only has good intentions. As evidenced by how many of these people think he reminded Charlie of his dead boyfriend who was "Asian" according to them. Did they not even pay attention? A) We see pics of him and he was a white guy, the sister even says she was adopted b) The delivery guy is an Indian dude. I know to the average imbecilic Redditor that Chinese = East Indian = all the same, but they hit a new low this time. They also predictably think the Bible boy was the only true evil one, for trying to cure Charlie of his gayness. An idiotic immature kid, sure, but only on reddit would they somehow find the delivery guy heroic and the kid a monster.
