As a non American, I sometimes just enjoy deliberately messing a bit with Americans when they utter these expressions, by doing it over the top. Someone meeting me for some boring work related thingie: "Hi! How are you doing?" Me: "Super awesome, thanks so much for asking! Super excited to meet you and discuss this!". They probably think I'm crazy and/or are not sure what to make of it, so it's fun to see the puzzled…
As an American, I wouldn’t blink twice at your response...
Which I took for "What the hell is wrong with you, crazy foreigner who doesn't know how to read social cues"
