Why do shop aisles seem emptier but more crowded?
The short answer
A Moroccan [souk](https://slowmorocco.com/glossary#souk) shop stacks goods floor to ceiling with the shopkeeper sitting in the middle. The browsable space is whatever remains — often less than a square metre.
The density forces engagement. You can't browse at arm's length. You end up touching, picking up, turning things over. Every interaction is physically close — conversation distance, not browsing distance.
Two people in a souk stall is a crowd because the stall was designed for one customer at a time — one conversation, one negotiation, one transaction.
