I think you are addressing me? Part time I do.
I make sure the owner, who knows these guys better then I do, decides when someone can't buy a light and there is no chance of a sale, before handing out one of my old lights. Some of the regulars are special needs, a couple are homeless. Some are just out of money and they need the bike to get around. Some are on some kind of assistance.
A couple of the special needs guys break a light once in a while. One guy rides all the way across the city in the dark, even without a light. We try to help him if possible, somehow he breaks his lights. He's been coming to that shop for maybe 15 years, along with a couple others. They are steady customers and pay for things like
a chain and a cassette, every couple of years etc. They come on the Wednesday night slow ride once in a while. Depending on what the parent or guardian says.
I ride home with one guy who is not allowed to ride home in the dark alone.
He has a 35 lb bike with tons of junk on it, at least 40 lb total. Last week I could not catch him on the big uphill. I was on my 17 lb Litespeed with Ksyriums.
