I ask anyone who is by the side of the road, unless they are obviously fixing something themselves or on the phone. Not that I could help with much, but I do have basic flat changing stuff and extra tubes.
Last fall I was riding with one friend; I came to a stop sign and made a left. After I turned, I stopped to wait for my friend. At the intersection there was one of those New England type triangle intersections, with a small "green" in the middle. Two guys, around my age were lying/sitting on the grass, with their bikes laying on their sides. I asked if they needed help, they waved me off, without even a thank you. After my friend got there, and I was taking off some layers, I noticed one of the guys' wives driving up in a Cadillac Escalade, and putting their bikes in the car. I think they just were tired of the hills around here!
