On Thursday evening this week a male enters store goes to kiosk and purchases a drink and pays with a £50 note. Once transaction goes through the male pull a few more £50 notes out and asks for notes to be changed, Once changed male pulled out more £50 notes and wants more changed colleague says you need to purchase something so male keeps buying £1 scratch cards and changes the notes over. The notes feel different and the green line down the middle was a darker colour and the £50 in the top corner is bigger than a normal note.
