Most places have laws against tipping to employees that don't interact with customers in transaction. So owners, cooks, and managers legally can't get tips.
Edit: But those laws probably aren't followed at some establishments
That does depend on the state though too. I worked in a restaurant where any tip on take-out/drive-thru/catering was spread among the kitchen staff. No manager can receive tips, but at least the staff preparing and packaging the food still have an opportunity to earn something extra. When I worked there, because of the tips, I earned an extra $2-$3 a shift.
