I have always preferred to sit in my car to eat at a park or some relatively peaceful place in the shade without too much activity. Sitting in a big dirty room with a bunch of people watching me eat has never been comfortable.
I agree. I can listen to a podcast in my car, there's no chance someone will cough or sneeze near me, etc.
My first time being into a McDonalds since I was a kid was earlier this summer when I gave my 3 year old the option of going in or staying in the car. I was pretty shocked at how barebones it was now. There weren't even napkins available and none with our food...which, when you have a kid with, is an issue.
