Most people can't imagine leaving the house without having their mobile phone on them.
And French fencer Enzo Lefort must have been so worried about missing any calls or text messages that he tucked his device in his back pocket despite taking part in an Olympic bout.
But the 24-year-old was left red-faced after it fell out of his trousers and skidded across the floor during his individual foil match with Germany's Peter Joppich.
The French and German fighters were pitted against each other during the fight at the Carioca Arena in Rio on Sunday and immediately began lunging at each other during their qualifying match.
Lefort's mobile phone was spotted tucked away in his back pocket as the pair continued to advance on one another.
