Cool, thanks for the write-up! Yeah, I knew that dude would be the limiting factor and that this wouldn't be a contract for any kind of speed competition. It was more of a fun flavorful thing just to do something with that guy. I hate that one of the level's three exits is essentially unusable because of that stupid clerk.
I found that if you grab a waiter uniform from the wine store en route, you can poison his water early, but it doesn't really help with anything.
My contracts are up on HitmanDB! I'm excited about that thing.
