On recent holiday in Colorado, went to a store in Breck village. It was a fairly big store selling just helmets and goggles I think, don't recall the name (on a corner of the main street, 2 storey). My wife tried on helmets for some time trying to find right fit, and one she did up tightest it would go on the chin strap, but it swivelled back and forth well off her head, the sales assistant told us "that's all good, and you don't want a helmet to be tight, and lots of dudes just wear theres undone, and that it should move around" !
Haha LOL, fortunately we are not retarded and left the store. Unbelievable guys are handing out this "advise" to people.
I guess if people believe that, then a little more serious head trauma wont make much more difference to them. But it does suck that guys put a sale over people's safety. Assholes.
