I regularly do scan as you shop and have started to notice some patterns in auditing. If I change my mind on a product and remove it from the basket while shopping I'll get audited almost every time, similarly if I add a single onion (which is a weighed product) to my basket. I do enjoy the company line of asking "did you have trouble scanning anything" just before they do the check, which is blatantly a get out of jail free card to say "oh, yes, I did in fact have some trouble scanning that 42" TV that doesn't appear in the basket currently".
