Bizarre Dinner Wishes

So...went to dinner last night with a supplier for a going away dinner....they told the waiter and he gave me a free dessert and slipped me a little card in an envelope....no clue what it was...I opened it later and it was a card that says "Best Wishes" and then has a lot of signatures (Noah, Dri, Laura, Crystal, Christina, Mark, Natalie)....who are these people....seems they work at the restaurant....soooo bizarre!!!!!!!
