Just had lunch at Aquitaine, and I had to share this experience. It's Friday, Restaurant Week, and they're slammed.
The waiter sets my co-worker's club sandwich in front of her, she starts nibbling on the accompanying fries. Seconds later, the waiter returns, tells us that there's no mayo on the club, and that he needs it back. She gives it to him and he replaces it with another.
We then watch as the first, mayo-less club returns to the counter where the servers pick up completed dishes. It sits for about 10 min. and is then picked up and delivered to a diner at another table (sans the couple of fries my co-worker ate).
I didn't say anything (I should have, right?), but it definitely struck me as pretty gross.
