This backpacker has taken inconsiderate travel behaviour to a whole new level.

A video of a backpacker has gone viral after she refused to remove her feet from the seat next to a fellow passenger’s head.

While travelling recently from Bangkok to Sukhothai province in northern Thailand, Narong Thaopanya, was horrified when the bus passenger behind him put her feet onto the seat next to him and refused to remove them.

The 21-year-old filmed the incident and posted it on social media.

Thaopanya said he was overcome by a rancid smell from the moment the fellow bus-goer sat down behind him and put her "sweaty socked" feet on the headrest of the chair beside him.

He politely asked the woman to remove her feet, however, he claims she refused to listen, stared back at him, and put her feet back up on the seat.

“This woman’s face was beautiful but she had no manners,” he reportedly wrote on social media.

“The smell from her feet was filling the whole bus – it was hot and made me feel sick, because her feet were next to my head."

"I asked her many times to put her legs on the ground and she would not do it. She just kept them in the air.

"Somebody will have to use the seat and put their head where her dirty feet have been."

Of course, this is not the first time travelers have been called out for their inconsiderate behaviour on public transport.

Last year, Boston Globe columnist Dante Ramos tweeted an image of a woman’s ponytail flung over the back of her airplane chair. While this might have been very comfortable for her, her long hair obstructed the view of Ramos’ partner’s screen.

“At first I thought, ‘What is that?'” Ramos told metro.co.uk.

“It took us a few moments to figure out that it was another passenger’s hair.”

The woman seemed confused when Ramos’ partner Ryan stood up to speak to her.

According to Ramos, the offending passenger then moved her chair forward and her hair no longer obstructed the screen.

Only last week a woman was caught eating pistachios on a plane and throwing the shells on the plane floor.

A Reddit user who spotted the woman took a photo and posted it on the site.

The post attracted a lot of comments, with some calling out the woman's obscene behaviour while calling her "trash" and an "ignorant idiot".

Others came to her defence, saying the carpet would get a vacuum at the end of the flight, while others criticised the photographer for not taking action during the flight.

Have you ever had to deal with someone else's rude behaviour while traveling?
