Working in retail can be very rewarding, but it has its downsides - don't get us started on those Boxing Day shifts.
Take, for example, Katy Cottrell, who works in Topman. She had innocently gone about her day, doing her job to the best of her ability.

She received an Instagram message at 11.17pm last night from the girlfriend of a customer (whom she, no doubt, has no memory of whatsoever) basically warning her that she shouldn't have asked for his e-mail address because he's not single.
Why did Katy ask for his e-mail address? To send him an e-receipt. It's standard practice in most high street stores nowadays. We're trying to save the planet, people.
The bemused shop worker shared the message on Twitter, saying: "E-receipts ruining my life."
It read: "Hiya chick, you don't [know] me but my boyfriend followed you on Instagram today.
"He said you work at top man and asked for his email? Im (sic) sure you didn't mean any harm but he has a girlfriend so please can you block him on Instagram.
"Sorry haha don't want to be mean xxx"

To be fair, it's friendly enough. But surely she should be asking her boyfriend about this.
So many questions. How did this man find his Topman server on Instagram in the first place?
Why is this girlfriend not taking it up with him and asking Katy to block him instead?
Kate's tweet has proved very popular, being retweeted over 6,000 times and 'liked' over 20,000 times.
One person had the perfect solution
But we're not sure that would have helped at all.
If you are the Topman customer (or know him) we'd love to hear from you. E-mail firstname.lastname@example.org.
