Martial Arts advice

Piss poor IMHO and pretty unusual for BJJ places from my (admittedly not huge) experience. I'd definitely try somewhere else. Whereabouts are you located?

I went to a BJJ class tonight with a mate. My mate has been training for the last couple of months in Portugal whilst he has been there. We picked a gym and emailed them to get ourselves into an introductory class. After the warm up, the instructor demonstrated a move a couple of times and then people paired up to practice it.

As a relative beginner and a complete beginner, we were not exactly perfect. When we asked for a bit of assistance, the instructor told us that he wouldn't help us as we had not committed to the gym, that he had to help the others, and that anyway, he was part way through a cycle of techniques and we should try to get on with it. The result was that we grappled and watched others as best we could for about 40mins of a 1hr class.

I thought that this was pretty piss poor, and am unlikely to return as a result. Is this usual? Or would I be better off trying a couple of places?
