A taxi driver caught the moment a woman let a young boy poop outside Burberry in designer shopping outlet Bicester Village on camera.

"I'm guessing she's not a @Burberry fan".

The picture has garnered hundreds of retweets, with shocked Twitter users expressing their disgust.
But some horrified users apologised on behalf of the tourist, with 'yellow lele' replying:

Perhaps we should take a leaf out of their book and start apologising for badly behaved Brits abroad?
