Wanna get your McD meals without the hassle of standing in a line waiting for your turn to get your orders taken? Go to their drive thru whenever possible. You'll be sitting in your car, your orders are taken real quick, and best of all, you don't have to wait for long compared to standing in the line at their walk in counters.
After that, you may opt to stay in your car or bring the food into their premises to enjoy after you found a parking spot (free wi-fi, mind you).
Bonus: you get a brown bag and cup/drink holder too.
