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.

Another commuter who spotted him wrote on Twitter : "Dirty git has been rubbing his trotters on the armrest and seat throughout." He told Bristol Live the smelly socks were on display for most of the journey.
And sadly it seems this is a growing trend on trains. After posting his picture on social media, others replied with similar images of people with their feet on seats.
It's a topic that gets debated on Reddit regularly. One person wrote: "Pretty simple, don't put your feet on the seat, there are signs everywhere telling you not to do so."
Another wrote: "I’ve seen women take off their shoes and rest their smelly feet on the chair opposite. Yuck. The whole feet resting thing is just gross." A third penned: "They have no respect for anyone ..were dragged up."

But there were a few people defending the act, one person wrote: "I don’t think it’s ok, but I kind of get why people do it - the train is a public space, not a private one, so it’s not seen as specifically owned by anyone.
"People don’t feel responsible to anyone for putting their feet up. Would they do it in their aunts house? Of course not. They’d feel they’d be insulting their aunt. "
