Shops like these are great while cycling the Atlas Mountain Race or any other biking or hiking adventure. Don't expect a western supermarket, but just what you need when you're hungry and thirsty.
The guy at this shop has quite some stuff for resupply! I was told that a bit further up the road there is a restaurant and even a hotel. I didn't check it out, but instead got coca-cola, yoghurt and lot of sugary cookie-bars and salty crisps here.
