Yogurts that state "thick & creamy" on the label but they are like flavoured water inside.
Ordering steak at a restaurant and, regardless of how you ask for it to be cooked, it still arrives on your plate as medium rare.(Miller & Carter are buggers for this)

People who will have a cooked breakfast or Sunday roast etc and eat all the items in turn instead of mixing the flavours.
