I'm a little confused myself lol but I was mostly talking about their economy service. From DXB > SYD just in March I experienced some terrible service.
I think the only good part was when I requested to be moved from the family of literally 10 because of the horrid cough I was developing - mainly because I was sick of their dirty looks.
I guess if they want to have fun - go for your life, but don't be unprofessional. I myself have personally never witnessed this though.
