Musar zu Bereschit 24:32

This is why he immediately brought Eliezer and his entourage to his home, prepared fodder, etc. He did not do this out of charitable considerations. This is also the reason he preempted his father and asserted that since the match was made in Heaven, they could certainly not object. He was afraid that his father would come up with some scheme to delay this match. He was anxious to earn the fee that Eliezer had promised him. As soon as Eliezer had heard Laban say "here is Rebeccah, take her and be on your way," Eliezer thought that the matter had been finalised; he thanked G–d and brought out all kinds of golden and silver trinkets as well as costly garments, as described in 24,52. He gave all to Rebeccah, whereas he gave Laban and his family only exotic fruit and other delicacies.
