Like many rogues, my character likes to cheat at cards and steal from NPCs if he thinks they deserve it.
However, the vast majority of D&D towns are small enough that everyone knows everyone. I'm yet to visit a town in my current game where someone hasn't mentioned that they don't recognise me therefore I must be a newcomer.
How can I act like a rogue without the townsfolk immediately putting two and two together that I'm the one responsible for thefts, even if I disguise and sneak perfectly? After all, nobody's stolen anything for years until I showed up (because it's a small town and everyone knows everyone). I'd quite like to be able to use my huge stealth/deception modifiers to avoid becoming an outlaw of each town by default.
