Good job you didn’t start you post with,
“Save me from mechanically inept road cyclists”
When I pointed the guy out to my girlfriend and told her what he’d said, she said “stop being such a bloody snob.”
“How can I be a snob when he’s got a more expensive bike than me and he doesn’t even know how to fix a puncture?” I replied.
She walked off without saying anything else. I assume that was because my point was irrefutable.
