Was the pilot of my flight unprofessional ?

I was flying from Philadelphia to Buffalo, NY with US Airways Express, operated by Republic Airways, and even though it was a short flight, the flight attendants and the pilot seemed very unprofessional. Before leaving the gate, one of the flight attendants walked in, she was obviously late, and chatting on her cell phone. Both flights attendants looked miserable and hostile, which is something you can come across on any airline, but when the flight attendant was making announcements, it was impossible to understand what he was saying because he wasn't speaking clearly. When the pilot came on, he warned us that we would be experiencing turbulence because "the air is pretty messed up up there so make sure you hold on". That’s exactly what he said, and he wasn’t trying to be funny, he didn’t seem to know what to say, mostly just random comments and it was hard to understand what he was saying. When we got into the air, the pilot came on again and said that the seatbelt sign would remain on for most of the flight, but that "you can take your seat belt off if you want but uhh that’s at your own risk, the air is just really messed up "… why would a pilot say such a thing? It was the worst flight service I’ve ever encountered. The turbulence was horrible, and obviously the pilot can’t do anything about that, but they didn’t seem professional and that didn’t make me feel safe. Is that type of service considered standard for short flights or was it unprofessional?
