I've noticed in that several Voyager episodes that the Bolians are fixated with plumbing. Anybody know of a logical reason as to why?
JANEWAY: "I've gone through dozens of histories written about twenty first century Earth, all of them biased in one way or another. The Vulcans describe First Contact with a savagely illogical race. Ferengi talk about Wall Street as if it were holy ground. The Bolians express dismay at the low quality of human plumbing."
NEELIX: "Replicators aren't the only systems of convenience offline. We've only got four functioning lavatories for a ship of a hundred and fifty people."
JANEWAY: "I see."
NEELIX: "Needless to say, lines are beginning to form. If we don't get unstuck soon we may have a serious problem on our hands. Especially with the Bolians."
