conv: The other day I was at the store and the woman ahead of me acted like an alien who had never seen a self checkout machine. I wasn't in a hurry or anything but it was obnoxious that she was holding everyone up. I was at the store the other day and the lady ahead of me had no idea how to use self checkout_comma_ I wish she would have used the regular line instead of holding everyone up. Oh I hate when that happens. we go to self checkout to avoid things like slow lines. Exactly! I wasn't in a hurry or anything but it felt so inconsiderate. Hopefully the person learned what they had to do so they don't hold the line up in the future. We can only hope.
