People are very unkind about readers of science fiction and fantasy novels, portraying them as geeky virgins who still live with their parents. As a bookseller who has dealt with thousands of sci-fi fans over the years, I must protest at this crude generalisation. I have met at least seven science fiction readers who didn't conform to this stereotype.
My main issue with the sci-fi/fantasy fans was their relentless questions about forthcoming books. Giving customers information about new titles is part of a bookseller's job, but the fantasy readers nearly always drove me to a state of desperation.
'When's the next book in the Throngard saga coming out?' (We look books up by author and title, not saga and anyway, why are you asking me? Don't tell me you haven't spent ages looking at the author's website)
'Can you phone around your branches to see if they have a signed hardback of Terry Mobble's Planet of Woodlice?' (Of course; I've got nothing else to do)
'Is this any good?' (No of course it isn't, but it's got a map with a 'Western Sea' and some people with silly names and superfluous apostrophes - what more do you want?)
I became very adept at spotting any potential sci-fi/fantasy enquiries and would quickly hide, leaving the less experienced members of staff to learn the hard way. I felt a guilty pleasure at overhearing them say 'Sorry, but how do you spell P'taneth Mhoordu? Is it one word or two?'
