Salaam. I'm Mahmoud. I’m a Zamzam water server. I carry bottles and cups for visitors. I do it with respect and with a smile. Zamzam water is special. It’s a blessing. People come from all over the world. I help them stay cool and hydrated. This is an honor for me. My father did this job. Now I do. I want you to serve others. Even in small ways. Holding a door. Pouring water. Service is a beautiful thing.
