I’m really disappointed with McDonald’s. Every time I order my burger without pickles, they still put them in anyway. It’s like they don’t even read the order. And today was even worse — I paid for a large meal, but the fries box was only half full. If I’m paying for a large, I expect to actually get a large. Very frustrating experience.
