How about the Trader Joe's line? For those that don't know, there are two lines (express, non-express) that extend the entire perimeter of the store. I'm not joking, the line goes through aisles and blocks you from getting certain things.
The trick to this is to gather all the items not bordering the line, then get in line and shop while you advance in line.
