No, I'd say it's work expectations that have increased the number.

I took a several-month career gap and didn't order delivery even once. Delivered food tastes bad and as long as I have time I either make food (most of the time) or dine-in. But when "everything is on fire" and deadlines are tonight, delivery it is.
