I'm standing at a cash desk, waiting to pay for my weekly shop. But there's no beep of the tills, nor bright overhead lighting – just a serene backdrop of potted plants hanging from the ceiling.
Where you would normally find bags of crisps and packets of chewing gum, there are shelves of locally-delivered freshly-baked cakes, cookies and sourdough bread.
Far away from my usual discounter supermarket, I'm at London's first zero waste shop.
Bulk Market, currently functioning in pop-up guise on Dalston's Kingsland Road while crowdfunding to open a permanent space, was opened by founder Ingrid Caldironi in response to the volume of waste produced by traditional shops. (According to research by Wrap UK, supermarkets wasted 235,000 tonnes of food in 2015, and, out of the 170 million tonnes of waste the UK produces each year, a large amount is food packaging).
When I arrived, I was taken though the process. If you haven't brought your own jars, bags, wicker baskets or takeaway Tupperware (the most popular option), you can take what you need from the free jar bank, or grab a compostable bag.
Ingrid's personal crack at going zero waste inspired the move to open up. "I went waste-free two years ago and I had an absolutely crazy time trying to incorporate it into my lifestyle," she tells me.
The shop is a modern take on the old school way of buying groceries and household goods. An array of pick-n-mix-esque glass jars line an entire wall and are stacked on shelves all over the store.
Beans, rice, pasta, sugar and spaghetti are available by the gram. I'm encouraged to pour as much as is needed into a glass jar. No more, no less.
Cost-wise, almond milk from a giant Kilner is 40p per 100ml, Jarr kombucha comes in at £1 for 100ml and organic maple syrup is £3.89 per 100ml. Organic Italian pasta (available in either plain or wholewheat) is 40p per 100g, potato/grain and seed sourdough bread is £3.38 for 500g and you can grab a bamboo toothbrush for £2.69.
I move along and find UK-produced cheddar and goat's cheeses sit in a small fridge, and barrels of organic washing up liquid, laundry detergent and all-purpose cleaner are ready to be decanted into glass bottles.
"The unique thing about Bulk Market is that you have everything all one place," Ingrid tells me.
It really does feel like she's thought of everything. The beauty section is decked with jars of essential oils, cocoa butters, powder deodorants and package-free soap, which hum with the scent of essential oils.
Storage space is extremely minimal, meaning that Ingrid only orders new produce when she absolutely needs to.
"It's important for us to stay in tune with what our customers want, so that less popular products don't go to waste unnecessarily."
There's skills to be learnt, too: I blend peanuts into nut butter, try grinding my own coffee from dark, chocolate-y beans and mix moisturiser from cocoa butter.
According to Ingrid, customers have likened their experiences to a time before supermarkets. Hand-picked, researched and sourced with a personal touch, I can't disagree.
The experience itself may be decidedly retro, but this could undoubtedly be the future of grocery shopping. Less destinations to hit to get what you need, less harmful packaging and products, more natural and locally-sourced products and, most importantly, less waste. Only taking what we need.
There is no self-service option, and no garbled robotic voice telling you how, when, or where to pay. My items are weighed, the weight of my reusable jars deducted, and then I hand over my debit card.
Behind Ingrid, '#ZeroWaste' glows in red neon on the wall behind her.
I leave, confident that the past has got to be the future.
