Right. What's so "Er" about that? Maybe you don't notice that you hired an ax murderer until the third month.
What's the incentive to not request a refund on day 22? (Besides being a tremendous douche.)
P.S., Joel, apparently you hired one of my friends as a summer intern. This guy is smart, earnest, and great to be around. What a good catch. I'm gonna try to finagle a Fog Creek visit through him ;)
