From Wookiepedia's entry on Bodhi: "Though he was a very experienced pilot, he had a tendency to be tense and hot-headed."

Anything where suspicious rebels think softspoken and quiet former imperial Bodhi is an easy victim, only to try to pick a fight with him and walk away with their lunch trays cracked over their heads. Bodhi didn't survive this long with the Empire by letting himself be walked all over.
