Dear Will
Not to worry, we are safe. Our own black hole, Sagittarius A, does have an appetite for objects that get too close but if a star has enough tangential velocity it will orbit the black hole in a Keplerian orbit. For example in our own solar system the sun would consume the earth if it were headed directly toward the sun. Fortunately we are safe in a more or less circular Keplarian orbit. Astronomers have kept track of a few stars around Sag-A for a number of years and their trajectories fit nicely with the theory of orbits.
If there is a gas surrounding a black hole the random collisions within the gas cloud can allow some particles to get too close to the 'event horizon'. At that point there is no escape and the particle is a gonner.
