they don't require skill to do what they do
Hmmm... if I told my missus that making sure she always looks good for work (which is a requirement of the job, and failing to do so can lead to negative actions) didn't require any skill - my gentlemans vegetables would be in jeopardy.
Grid-girls don't add anything to the racing and, honestly, they are a pointless distraction from the true stars of the racetrack: the cars and their drivers.
For any true racing fan, there is more than enough "pr0n" on the grid already,
Poor attitude, especially the bit in bold.
I bust my ass and make many sacrifices to visit as many motor races as I can, because I love it, I've spent a lot of money and time doing it. I happen to enjoy the tapestry of senses that a racing event offers, many, many things form that experience, grid girls are just one. There's
plenty of other things going on that aren't directly related to racing, and sacrificing them because you've got some ridiculous notion that events should be about the purity of racing is simply narrow-minded.
You don't need a display of supercars in the paddock to enjoy the racing, or parachute displays, or fly-pasts... you don't need stunt demos, bands or DJ's... you don't need auto-club meets, or manufacturer displays. You don't need ferris-wheels, or fairground rides, or fireworks. You don't need promo people, grid girls, leaflet givers, people selling die-casts, team gear, tools, books, souvenirs, car-cleaning products, candy floss or pic'n'mix. You don't need autograph sessions, or driver interviews... you don't need the Tuborg beer bus...
... but going to events like that is frankly a bit dull (and could well mean the difference between the circuit getting my money for a Week/Weekend/Camping or Sunday only ticket).
I'll be honest, I take photos as a hobby, up to several thousand per event. Mostly of the cars, but it is nice to point the camera at other things, and yes, one of those things is the grid girls... other things might include, drivers, lorries, stunt bikes, architecture, cars in the car park, flags, clouds, mushrooms, grass, concrete, birds, tyres, air-guns, food, pints of beer, rain drops, other peoples cameras, marshals standing in the way... I do this because I like to capture my experience. If people think it's just a grubby little fascination with looking at pretty girls, they can **** off with their ignorant perception of my hobby.
