I'm pretty welcoming and gregarious, I have had random people join my team before when they asked (my teammates were less comfortable at first, but relaxed and welcomed them later). This will definitely depend on the crowd. It may be easier to start your own team (or playing solo at the bar) and just start getting to know the other teams for a while first before asking to join them.

It also depends on the location. One is a restaurant, people are generally less welcoming to random folks sitting at their dining table (unfortunately). The other location is a bar. It's much easier to just join a random team. Find 3 people sitting at the bar and ask if you can join them. Or, like the last folks that joined us, find a table with several empty seats and ask to join them.
