Police have revealed that missing British hiker Esther Dingley's home life "was not as idyllic as social media suggested" as footage was taken just days before her fateful walk.
The CCTV video shows Miss Dingley in a supermarket in the Spanish Pyrenees where a shopper who saw her described her as "sad and pensive".
The 37-year-old fitness enthusiast challenged the staff at the Eroski store in Benasque over the price of a pack of chia seeds as she made her march over the mountains on Thursday, November 19.
A local English teacher comes to her rescue when Esther fails to understand the manager's explanation of the discrepancy in the cost of her purchase – as she couldn't understand Spanish.

The footage was released when investigator Capitaine Bordinaro, who heads the French part of the Franco-Spanish joint investigation, stated after an interview with Ms. Dingley's partner that the couple's life "was not as idyllic as the one on social media published images suggest ".
Bordinaro told MailOnline: “We interviewed Daniel Colegate on Monday in the farmhouse where he lives in the Gers department.
“We want to examine all possibilities. We do not regulate any request.

“But it doesn't seem likely that Esther was in an accident, and it is not believable that she was eaten by a bear or fell into a lake.
"We believe that their disappearance is either the result of some voluntary act or the result of someone else's act."
“We visited Mr. Colegate so we could go social media with him – news etc.
“It seems that their life together was not as happy as the images posted on social media suggest.
"However, I would like to emphasize that we interviewed Mr. Colegate as a witness and not a suspect."
The Oxford graduate was interviewed last week by French gendarmes and the Spanish Civil Guard about Esther's disappearance.
37-year-old Esther Dingley was wandering the Pyrenees on the border between France and Spain when she disappeared, resulting in a search and rescue operation that has since been suspended due to weather conditions

In the supermarket, the chia seeds were marked with a discount that was only valid for buyers who had a customer card, explained Maria-Carmen – the teacher who helped Ms. Dingley in the store.
Maria-Carmen told MailOnline: “Esther wanted to buy a pack of chia seeds that were reduced. However, you will only receive the discount if you have the Eroski customer card.
“The girl at the checkout tried to explain it to her, but she doesn't understand because she doesn't speak Spanish.
So the girl called me and I came to explain to her.
"She said it didn't matter and bought the seeds one way or another.
"We didn't talk for long because I was on my way to work, but she seemed sad and thoughtful."
Esther stayed in his 7,000-foot Angel Orus Refuge (pictured) on November 17th and appeared to be "in a very good mood".
Esther was also seen two days later practicing yoga movements in the parking lot where she had parked her Fiat motorhome.
Maria-Carmen explained: “A few days later I saw her doing yoga on the street next to her mobile home.
“It is not a common sight to see someone on the street doing Benasque Yoga, so I noticed.
I later heard that the English woman Esther had disappeared and I contacted the police and told them I had helped her.
"I just hope she's okay."
Meanwhile, Ms. Dingley's partner has been interviewed for the third time by police about her disappearance, MailOnline can reveal.
Four officers of the paramilitary forces of the French gendarmerie spoke to Daniel Colegate in the farmhouse in Gascony that he was sitting at home on Monday afternoon.
Colegate, 38, had stayed on vacation for £ 1,000 a week while longtime partner Esther went on a solo hike in the Pyrenees last month.
Bordinaro alleged that Mr Colegate was questioned as a witness and not a suspect.
