I think he’s looking for his 15 minutes of fame, and wouldn’t be surprised if he sues Primark, looking for easy money. I work in retail, and I can’t begin to tell you the bizarre stories our customers come up with when they’re trying to make a quick buck off of the store I work for (which, by the way, they usually get). The more outrageous the story, the less likely I am to believe it.
