QR lever not properly closed - do you tell them?
So, I've happened to follow the same bloke on my way home along my new commuter route, a few times now.
His QR lever on his rear wheel is always sticking out at right angles to the rest of the bike, glinting prettily in the sun, and it falls somewhere between irritating me and worrying me.
Is there a polite way of bringing this to his attention - for him to at least check it! - without seeming like a know-it-all poking my nose in where it isn't wanted?
