Do that about a hundred times and you've turned $10k of dirty money into slightly less clean stuff with zero risk.
Not many people would use hundreds though. When you put the hundred in, the self service thing would record it in the system with a timestamp. Then they match the time with the cameras......I wouldn't say zero risk. The reason they wouldn't like you using $100 notes is because - the woolworths ones, the coles ones are better - give out $5 notes as the largest denomination for your change.
