The random anti-intellectual comments from the guys in the wheely chairs were extremely annoying and unfunny. This guy is there, showing something truly amazing, and they're all "What's an algorithm? Haha!". And they'll get away with it too.
"OH, oh I'm sorry, but this is abuse."
"Oh, I see, well, that explains it."
"Ah yes, you want room 12A, Just along the corridor."
Honestly though, if people were enjoying them, I don't think it's any less rude. It says more to me about the anti-intellectualism mentioned earlier. Reminds me of the Diesel campaign surrounding the word "Stupid".
I don't know, I think you can nail this kind of repartee and it's funny and makes things flow - which stops the day from getting boring and stiff. But I hate it when it's not quite right. Kinda like the MC at a gig who tries to make bad jokes and ends up being super awkward.
It was a pretty funny way of asking for more details imho.
