I walked past this truck a little while ago and was delighted by it. It was on-site where a crew was filming a movie, something you see more and more of these days on the streets of Beirut. Inside the truck I could see a little kitchen and there were also bathrooms (see the door marked for men, just to the right of the logo?).
A brilliant idea. If I were filming a movie, I'd definitely want this truck there. Creature comforts matter.
