Aldi - because I have adhd and possibly some autistic traits and it’s regulated and not over stimulating.
There is no music, the lighting is good. The price is always displayed in the same place relative to the product. And it’s very rarely wrong.
The special offers are straightforward price drops, not 2 for 1 where I have to think if I want to buy that much, or do calculations in my head that disrupt my running total.
the quality is consistent. The labelling is straightforward so you can see country or origin at a glance.
the trolleys are in good condition and work.
And in my branch the staff are lovely, don’t start scanning before the last customer has cleared off, and are really helpful in general (I know that might be our branch in particular)
having said that they used to be much more neurodiverse friendly before they “improved” the look of the store and added an extra aisle that leaves you at the back wall instead of at the checkouts, extended the aisles into the queuing area, and started having cardboard stand alone shelves of unpriced branded products cluttering up the checkout area.
but it’s still a much easier shopping experience than any other supermarket even during their token autism friendly hours.
