It's possible you've spotted these book stalls dotted around Dubai, so here's the concept.
Book Hero runs entirely on public trust. No staff, no tills and it's open 24 hours a day, every day.
See a book you like? Simply drop your cash in the 'Trust Box' to make your payment. Books will be marked with the price (usually between AED10 and AED 20).
The entire operation is the ultimate proof of what an incredibly safe city Dubai is to live.
