The small outfit I've been with is owned by a big fortune 100 company, and they've been reeling in some of the divisions that aren't deemed core to our business - HR, IT, Legal, etc..., and making them into corporate chargeback services to all their subsidiaries. The differences in business models and culture between our companies is staggering, and it gets pretty comical (and sad) at times working with (or around) them for these services.

Didn't see mention of Gibson there, though...
