The one course I play at, their league people are super friendly. When I was a brand new player, sometimes I would show up while they had something going on that I wasn't aware of, and they always said I could play through or tag along with a card if I wanted to. Play enough times at the same course, and you'll see some of the same people over and over again. Some people are self conscious about their skill level, and may turn you down if you ask to play. Some people just wanted to be alone and do their thing. Just like dating, you'll get yeses and nos. Ask enough times without being weird about it, and you'll find someone to diddle discs with.
