one thing to get used to is that you are flying a limousine not driving a bus, passenger comfort is right at the top of the list of priorities especially if it is a one owner aircraft. It makes a nice challenge not to have his/her G&T slide off the highly polished walnut table into the lap of his/her Gucci suit, especially while taxying .
and if he/she says not to wake them up with the seat belt light they mean it, they ignore it anyway.
