In the future, it would be worth considering making a telephone call to the temple/vihara before attending. Just explain that you are unfamiliar with the practice at the temple and arrange/request contact with someone who could meet you there on the day, and provide some introductions and explanations. I attend a mainy Sri Lankan temple and that's how I began. There are not many westerners attending, though the monk is a German.
Alternatively, join a local lay meditation group and you are most likely to find someone in that group attending a temple in your vicinity.
Other than that, use the internet and do as many Retreats in a year that you are able to, and talk to us on DhammaWheel.
