We've all been there - you're on the loo, but you realise there's no toilet paper. It's an age-old problem, but in the 21st century one teen seems to have solved it.
Adam Greenwood tweeted for help - and got it.
The teen vlogger was stuck in a Virgin Trains toilet with no bog roll left, so he decided to tweet and ask the company's social media manager for help.
I've just had a reasonably large poo and there is no toilet roll left on the @virgintrains 19.30 train from Euston to Glasgow pls send help.— Adam (@AdamPlaysYT) December 2, 2014
He gave details of his location with almost military precision. Presumably expecting nothing to come from it, someone at Virgin's HQ asked for more information.
@AdamPlaysYT Which coach, Adam? ^MW— Virgin Trains (@VirginTrains) December 2, 2014
In case you were wondering, he was on coach J...
@VirginTrains J thank you— Adam (@AdamPlaysYT) December 2, 2014
Surely this is a joke? There's no way they'll actually send him some toilet paper through Twitter.
@AdamPlaysYT We'll send someone down to you ^MW— Virgin Trains (@VirginTrains) December 2, 2014
That's got to be a joke. That's just cruel. They wouldn't possibly do it.
Adam told BuzzFeed: "I got a tweet from Virgin Trains asking which carriage I was on, so I responded quickly by peering out the toilet room door and checking the carriage letter - this wasn’t awkward at all I swear.
"I tweeted back with the carriage number and I shortly after I saw a guy looking quite worried in a full black suit carrying toilet roll, after the awkward exchange and smiles I grabbed it off him and finished what I started!"
Having learnt his lesson, the 16-year-old will never travel unprepared again.
But what goes around comes around, and now Virgin's social media team needs help from Adam...
