Very complex kung fu move from 'Cashback'.

This is a brief, amusing scene from another movie I saw this week - and enjoyed. 'Cashback' was directed by Sean Ellis. The main character, Ben Willis is an art student who has just undergone a traumatic breakup with his girlfriend. As a result of the emotional upset , Ben has developed insomnia. To pass the night hours and to earn some income, he decides to work at a supermarket.
