According to our veggie store owner, they all buy the same thing from the central market, except that if he goes earlier he can pick the better looking stuff. If he goes later, he gets the leftovers. For the same price. Hence, he goes to the central market at 3 AM, comes back, sleep, and opens his store. That's a hard working guy.
However, he invites customers to pick their own stuff in his store, which is something very unhygienic. I thought he'd come to sense during the pandemics, but he did not. I don't like people who just touched the bus handles their nose, or their butt to touch the stuff I'll put in my mouth.
Here it's brought fom the capital by the wholesalers. Not that bothered by the handling of it as it'll be well handled already before it even reaches the shops.
