Travelling on busy trains can present a number of issues, from people sitting in your seat to loud passengers ruining the journey for others.
But one thing that is hailed as rude by most travellers is when someone dares to take off their shoes during the trip and expose their 'smelly' socks to the whole carriage to endure.
This is exactly what happened during one trip through London this week. A man ended up taking off his business shoes and 'rubbing' his feet on the chair, where someone else was destined to sit in the near future.
