OOOOOOh that cheeses me off SO much when they do that! Like, you saw me digging through the trolley to put things on the belt heaviest to lightest and in groups of cold, not cold, and not food, why are you ****ing with my system? Don't put it off to the side for another bag, but it in the same bag as the rest of the **** I put on the belt around it.
That reminds me of earlier this year ... I bought some groceries including cream and she messed with my system and put the cream off to the side to put with other things (don't ask me what) but she forgot to put it in any bag. When I went to use it for a very specific purpose later and it wasn't there I was really cranky. I sent Woolworths a really nasty email (while remembering why I don't shop there anymore) and they sent me a $30 gift card. It pays to complain (I got 4 dinner vouchers to Sizzler last week for writing a complaint to them as well )
