Ambulance chasers. A mostly unnecessary profession where someone "represents" the policyholder rather than the insurance company. They don't really do anything besides add a bunch of bullsh*t line items in Xactimate to try and "blow up" a claim. The end result is the claim extending for months and months and only the public adjuster benefiting financially, while completely screwing over the insured.
When my house burned down, a public adjuster solicited his services to me. Since I wasn't a moron, I told him to go f*ck over someone else.
