One of TransAD's taxi franchise that I prefer to go with is TAWASUL. I find that their cabs are cleaner than the others, even better smelling too. In addition to that, the ladies' taxi is good especially for the conservative ones who wish to have a lady driver instead; or when you just feel safer with one. I have had a bad experience though with one of their Filipina lady driver's though. She was a bit upset to see me again to be her customer as I was previously a customer who was just dropped of on a short distance and she recalled me. Thinking I am going on the same distance, refused to take me as she claims to be on queue for hours only to take a 15 dirham worth passenger. To her dismay I was off to a longer route. Despite the experience, I am still satisfied, and I actually prefer their drivers who know their way better and can understand common language. Unlike others who have language barriers, it would only either make you feel sorry or pissed.
