I recently went to a course on a Thursday afternoon after work and tried playing as a single walk-on. The attendent told me they didn't accept single players, and I would have to pair up with someone else or join a threesome.

I understand this practice speeds up play, but I'm new to the game, so I'm not really fond of hacking around with a seasoned threesome (plus I usually play nine holes). I only have one playing partner myself, and he doesn't have much time in the afternoon to play, so I'm in a tough position.

Why do some courses insist upon pairing you with someone? I suppose it wouldn't be such a big deal, but I usually play from the front tees because of my lack of distance. I know courses want to speed up play, but I usually proceed faster than most doubles.
