When I was young, a cousin would come to visit our family and take us out to a restaurant. Invariably, the maître de would tell him that he needed a reservation (or maybe only that there would be a long wait without one), and he would pull out some money and give it to the man, and we would soon be seated at a big table.
What's the halacha on that? Is that stealing someone else's position in line? If so, are both parties chayav?
