While the traditional British Royal Family member would not do these things given her circumstances, she seems like a strong woman.
Although Kate Middleton has cut down on her public appearances before giving birth to her third child with Prince William later this month, she was seen browsing the aisles of a store.
According to Daily Mail, the 36-year-old royal was visiting a branch of her favorite supermarket in Norfolk, before loading her Range Rover in the car park.
A shopper who was passing by photograph Middleton using her iPhone and claimed the Duchess bought a plant of coriander or parsley, with a '25 percent off' sticker.
The woman, who wanted to remain anonymous, said that when she followed her to her Range Rover, an onlooker greeted Midleton. He said: "Hello" to her and the Duchess replied: "Hi, hello."
"I was just in Waitrose doing a bit of shopping. I just went round the corner of the aisle - and I saw her. I said to my husband 'that looks like Kate Middleton'. He said 'it's not', and I said 'it is'," a passer-by said.
The royal was using the Quick Check system, which allows customers to scan and pack their shopping straight into bags in the trolley while walking the store.
The source said Midleton was doing her shopping at the store, but then, she saw her again 15 minutes outside when she approached her to greet her.
"I just saw her browsing. I didn't want to get too close to her," the woman added.
She also explained that Midleton was accompanied by a royal protection officer at all times, standing next to her as she loaded her shopping into the car.
The woman, who's not from the area and was returning from a holiday for the weekend when she visited the store, explained that it was a surreal experience to see Midleton doing everyday activities.
The royal seemed to have taken her own bags with her to the store, showing that she has the conservationist vein in her, or that she's just trying to support these measures.
Kate Midleton is expected to give birth to her third child, before the wedding of Prince Harry and Meghan Markle, on May 19, 2018, in Windsor, Berkshire.
