Well, I wasn't going to post my complaint, but since you asked...
I went to the grocery store today and I have never run into so many annoying people! This one couple was walking SO slow (no, they were not old) and every aisle I went in, they showed up. I even skipped aisles to avoid them, and they still found me! Then the guy I ended up in line behind had his cart overflowing and put the items up 1 at a time. I switched checkout lanes to a longer line, and got out ahead of him.
