High end restaurants absolutely do those! They track customers looking for whales, and track various random gifts and upgrades. "Monsieur? The maitre d' says he put the corner table aside for you. Please enjoy a small bisque while you wait, our compliments. And I believe it is your wife's birthday, perhaps the pianist can play her favorite song?"
Yes to whale-seeking, but this is otherwise not a valid comparison. Fine-dining patrons are not basing their visits around the hope that "this time they'll get the free appetizers."
Put another way, I'm reasonably sure that gambling addiction support groups outnumber fine dining addiction support groups by a few orders of magnitude.
