Show up, ask at the front desk if there's anyone looking to jump with other newbies. It might be a newbie, and it might be an old fart who likes jumping with newbies. Slow days increase your chance of jumping with the same person twice is more likely, and doing that will really make it easier for you to figure out what you're doing, so that you can either do more or less of it. But slow days decrease your chance of having someone at all -- ask at the front desk if there are people whom you normally should be looking for. Be honest that you can't afford to pay for coaching right now. And if you can afford to stay at the end of the day, do so, listen, and feel free to contribute beer if it's needed.
There's no guarantees, but it beats nothing.
