Okay, let me preface this by saying I don't expect a lot from a McDonald's.
Now, when I enter a drive thru at 1:38 in the morning, I just want to go home. I don't want to hear 5 whole minutes of BOTH employees chatting and laughing with the girls in the car in front of me. I also don't want to have to wait behind said car while they're talking at the second window. It took 17 minutes for me to get through everything. They were so interested in talking to the pretty girls that they let a line of at least 5 cars build up behind me.
On top of that, when I got home, there were only 8 chicken nuggets in my 10 piece and half of them were the size of a quarter. Out-fucking-rageous. Stop flirting and do your job.
