There's different ways of looking at this:
I've worked in pubs / clubs for many years, and usually the really big guys do come in with hot looking women (9 out of 10's). However, these chicks are usually all about their own appearance and just want someone nice looking (i.e. big guy) on their arm. Plus most of them spend the night shovelling shit up their noses.
The 7-8 out of 10 girls are usually nicer people, with a bit of personality as well.
But all this goes for the guys as well, we all want a hot looking girl, but most of them are not 'keepers'. That's fine when you just want to get laid, but for a long term thing you need someone with more about them or shit will get boring very quickly.
