I just watched the glass breaking at a Vape Shop episode. The glass breaks once to an employee and then a 2nd time to another employee. If you pause and look at the contents of the cases you will see that they simply reversed the image to make it appear that the glass broke on two separate occassions. The items in the shelf on the right were red and the glass broke. The shelf on the left the items were green, but when they show the glass break the 2nd time the items are now red.
