A Ride to a Wedding
A few friends are seeking a ride to a wedding. If the driver happens to owe money to any of them, may he offer the lender a ride?
May he give the lender preference over other people if there isn’t enough room for everyone?
The driver is allowed to give the lender a ride, since he probably would have done so regardless of the loan. If he is not friends with the lender, he would not be allowed to do so.
It is quoted in the name of Rav Elyashiv z”l that if he is friends with the lender, he may even give him preference over the others if there is not enough room for everyone, provided he is not doing it because of the loan rather out of friendship.
