The amount of empty platitudes in American English is sometimes downright bizarre. It's definitely the reason Buff isn't as concerned about his state than you were.

What I mean for non-Americans: A standard greeting in the US will be "How are you?/How are things?" The expected answer is, "Good, thanks." or "Good, and yourself?" If you answer honestly, (e.g. "Not great. / Pretty shitty.") you'll either get a strange look, or they will actually, and hilariously, reply "Good!" showing you that they weren't paying attention at all.

Not necessarily in the US! Implied consent clauses exist within the Good Samaritan Law. Not in Saph's case since he responded. It typically is invoked for some state of unconsciousness. Many European actually enforces duty to assist.
I'm also of the belief that if you want help, you should ask for it. I don't look highly of people who don't ask for help, then make remarks such as "All he/she did was watch". Likewise, I retort with "All you did was keep your mouth shut".
US Good Samaritan Laws allow bystanders to legally do nothing (except in certain states).
