n EZE while checking through the business class as a platinum elite, I made it clear that I had no bags to check in nor needed anything more than the boarding pass. The person checking me in was making small talk about my visit to Argentina etc...Then a supervisor stepped in and mentioned to him that I was just an elite passenger and not a business class passenger. Hence not to waste time on niceties with me. (I swear this took place right in front of me.)

Prefer the honest approach of just being efficient in checking me in and getting me there on time, instead of all the fakeness.
