Believing that the galaxy is a bottomless pit of scum and villainy does not make Bob a pessimist, he would argue. It just makes him a realist.
And you’d be pretty grumpy too if all your friends were morons and you’d been shot in the ass in every sector of Hoardspace. Bob likes money. Bob dislikes his job, his crew, his life, the universe and everything in it. Bob’s main talent is surviving sh*t - he's just really bad at giving a sh*t.
