Getting instruction with pax in the back

[farmpilot]

Hi all

Just wondered if anyone could help me out....... I was in Miami last week and wanted to do some sightseeing. I spoke to a company that had R44's on their books to see what we could do. I didn't have my licence with me at the time but still wanted to have a pole around the city. The pilot that I spoke to wouldn't let mrs farmpilot sit in the back if I was flying, so was just wondering if this is a specific FAA helicopter thing 'cos I've done it many times before in both fixed and rotary in other parts of the world.

Thanks all
