Depends on the job, he might be a lawyer or something like that. Unlikely, I agree, but it's not out of the question.
Anyway, if serious, ~200-400 dollars lying about is a pretty normal amount for a professional of any field really, I'd expect to see much, much more if I'm honest. Having said that, this counts for single professionals, not 20-something year old junior workers killing their paycheck on Anime BD's.
