Yes, the superior among us usually dont show up unless you pay them off the books with such untaxed amenities. I had read a while back that cher would not attend poodle kerrys rally in new york unless she was flown there in a chartered jet. No jet, so she didnt go. babs streisand is also famous for demanding such pay off the books.
Sounds like tribute paid to mobsters, only less honorable.
Does she also demand you supply the RV she has follow her everywhere she goes, so she has a place to use the restroom?
