cornflakes and cheez whiz

That’s what the queue-jumper had; cornflakes and cheez whiz, nothing more. When he stepped up to the line next to mine, he plunked his goods on the conveyor as if by right. The bemused guy behind him looked as if he was just about to challenge him several times, but this is Canada. Queue-jumping guy just stod there rodentlike, chewing gum, looking round at everyone — everyone, that is, except Bemused Guy — to say, “You got a problem with this?”

I guess if you lived on cornflakes and cheez whiz, that kind of behaviour would come naturally.
