<prompt> Human: Three friends and I are planning a trip at the beginning of July and were looking into accommodations. All four of us are college students. We were originally looking into more affordable options like AirBNB, but the father of one friend was very insistent that for the friends safety, they had to stay in a hotel.The friend relayed to the other three of us that their father would use his frequent flyer miles to get a discountpay for a portion of the hotel fees they were not very clear on which at the time, so a hotel would not be out of range for us. I raised my concerns about cost several times. Yesterday, they told the rest of us that their father had booked the hotel without their knowledge, paying for it entirely in frequent flyer miles, and now wanted each of us to pay 25 697USD of the cost in the equivalent dollar amount and are claiming that because it was payed for in this manner, the miles could not be refunded.This all seems extremely fishy to me, and I doubt I need to explain that I dont have the money for sudden and enormous expense like this. There was no written or verbal agreement, but at the same time, Im concerned that if I back out, Ill be leaving my friends in a huge lurch. Im pretty sure he cant have the money collected, but if the three of us back out, Im concerned hell be charging his own child upwards of 2000, as they do not seem to be on good terms.  <response>: Tell your friends dad to pound sand. Hes trying to use his kid and kids friends to convert his miles to cash. Hes a dickhead.
