I'll do it if there's not a line. If there's a line, I'm not sitting in line for 30 minutes waiting to order and then waiting to get the food. Usually get this request after the 2am rush. I tell them in advance "Sir/Ma'am, I'll be happy to take you, but if there's a line, I'll have to drop you and complete the ride and you can ping back when you've gotten your order". They usually change their mind at that point.
