I just met someone named Joe at Robinwood. He used to be a real pro tennis player but he never won. He is homeless now and would coach for $10 an hour(because hes proud and won't take money from people)(my friend who knows him told me that). Hes a really good coach and he playing tennis all day. He won't tell me his last name and he says professional tennis doesn't make a lot of money if you don't win.
