Big hugs @Nefertari. Mention dollars and they'll start hopping. Tell them than you don't have medical clearance to drive yourself, and that you had set arrangements for a driver for the date and time as arranged. Advise them that as you no longer have an available driver because of their stuff up, you'll need them to pay a cab voucher both there and back home if they are unable to honour their original arrangements. Watch them very quickly fix their problem. You have enough of your own problems, without having to help them rectify theirs. Ally.
