Go for it! Just because I did it first (and I HIGHLY doubt I did) doesn't mean you can't make your own version, I would love to see a waiter Scout! (My shirt's clipping all over the place anyway, miscs don't really clip nicely with the default HWM model, but the Ticket Boy misc that was just added looks pretty good!)
The map is cp_studio_rc4 and springbreak_d which comes from the Bloody Good Time Map Pack, it's a very interesting map and it's got a great outside. Bloody Good Time Map Pack can be found here in the Maps folder.
