Chris was never taught concepts like "humility" or "gratitude" or "manners" growing up. That's why he's such a crude, selfish, entitled little hobgoblin of a person, and why you can totally believe he could be banned from someplace for not holding his gas in or act completely ungrateful when someone offers him (the "wrong" kind of) free food.
The whole scenario reminds me of a movie (can't remember what it was) scene where someone gives a homeless guy with a sign that reads "Need money for food" a sub sandwich. They start walking away as the bum looks at the sub in disgust, chucks the sammich back at the person, and screams "THE SIGN SAYS MONEY!" or something like that. That's basically Chris' behavior in these Tweets.
