Demons

Although they have gotten much bad press over the millenia, most demons are actually a pleasant and hard working sort who'd youd happily share a drink with in a local tavern.

It is meeting a demon while on the job that you wish to avoid. Since most demons work for evil gods they cannot disobey orders and most evil gods are unimaginative sadists who wouldn't give y ou the time of day while you're burning at the stake.
