The last time I went through a checkout the teenage girl had a massive tantrum at me and chucked all my shit into the trolly in a pile. The other staff did nothing. Never again.
Well if you work hard and save one day you will be able to go down to Kmart and buy yourself an extension. Maybe a spare room or that gym you've always wanted.
I can't think of anything worse than standing face to face with a complete stranger and feeling obliged to talk with them. Maybe thats why people have kids, so they don't have to talk to the check out operator.
