A man forgot the first rule of potty training when he decided to take a wee right in the middle of a Mark and Spencer store.

The mystery man casually walked into the M&S in Plymouth and wandered around for a few minutes, before making a bee line for the scarf rack and relieving himself, causing £280 worth of damage.

Several other shoppers can be seen nearby as he marks his territory, however they either don’t notice what he is doing or are simply too shocked to do anything.

Unfortunately for the man (and the security guard who had to watch it), he was caught on CCTV.
