You Irk Me Things That Irk or Annoy Us

Come on do you really think you are kidding anyone when you order 3 hamburgers, 2 hot dogs, fries and onion rings and then you order a Diet Coke? I once stood behind someone in line and this is what they ordered and guess what it was for themselves. What is even funnier is that they actually turned around and said I am on a diet. I honestly hope they were joking. If you order food like that then a Diet Coke is not going to help. You need to order less. I know it was for them and them alone because they were part of my group and they ate it all in front of me. I wanted to tell them they needed to get help but then they might have gotten offended. What do you do in this situation? I just let it go, but this just irks me to no end. There is really no reason to order a Diet Coke when you have all of that other food unless you have diabetes or something but even then you should not be eating all of those other things so you really need to pay attention and instead go on a real diet.
