And it happens with government employees all the time, just a bit differently. The lobbyist is a member at Shinnecock Hills or some other private, prestigious golf course that costs $100,000+ to join. Then he invites the senator out, the "guest fee" is a nominal amount like $120, which he happily pays to play a round on a US Open quality course. Of course the senator charges his transportation and hotel to his office, paid out of campaign funds or something. Shit like this happens every single day, stop pretending to be so shocked or morally righteous.
