I work for a gambling company and the bet-pool/wager-resolution process happens with another company category called a 'tote'. For 49 of the US states we work with one particular company because we've identified them as being overall more competent and accurate. For the remaining state, regulations require that we work with a company with a 'local presence' in the state. There's only one company that fits that boundary, and they are somewhat awful to deal with. Not only do they constantly have problems, but they're not very responsive with business interactions. A good portion of our application infrastructure is dedicated to just handling the special case for this one state.

The state thinks it's doing good by forcing a monopoly for this one company with 'local presence', but the hilarious thing is that the company is HQ in Europe somewhere, and our preferred partner is actually US based.
