Weird news - Charter airline forces passengers to withdraw money from ATM's midway

Seems horrid. Imagine booking a charter airlines for your group, getting to the airport, getting all the formalities done, and finally taking off. You would have covered the most of your flight time relaxing, getting together with friends, and generally having a good time (and if you are on the return journey of your trip, you would be thinking about the good times that have been spent).
But would you ever think that at the midway flight stop, the airline would force you to withdraw additional money from any ATM that you could find, just so that you could complete your trip, else they would not leave the airport (and this is neither your departure nor your arrival airport).
What would you do in such a case ? You would mostly pay up, right ? You would be very angry, but you would pay up - which is what the people in this particular case also did (link to article):

A six-hour stay on the tarmac left passengers with no choice but to withdraw money from cash machines in the terminal building and pay the operator to complete the journey. The incident involved four chartered Austria-based carrier Comtel Air flights over the weekend and occurred during refuel stops in Vienna. Three of these have now reached Birmingham ; the other is said to be indefinitely delayed.
Dalvinder Batra, whose 80-year-old visually-challenged relative was forced to go without medicine during the ordeal, told the UK's Daily Mail website: "It is absolutely disgusting how they treated us. There are still people stuck out there. We have been told that the company has gone bust mid flight."
