Recommendation
If you go to a supermarket whose owners are Chinese, and perched on the till they've got an unsteady looking container full of lollipops and chocolate bars sticking out, be careful not to nudge one of the bars with your elbow, because without a shadow of a doubt the container will become unstable, the lollipops will crash to the floor making a terrible noise, and end up in a splintered, sticky mess.
