All the jobs I've had previously didn't really care about my birthmark, but I think people react to a pws'd hand differently than a pws face. Then again, I haven't really tried for an office job, so if I see my interviewer staring, I'll let you know.
I myself think that they'd really want to hire me- if they ever want to frame me for office espionage, they could always confront me without any evidence. Whatever the reason, I'm always caught red-handed. Badum pish!
