i use sometimes their service at Villagio parking or beside Eli France caffe. I find it convenient when my car is hell dirty and my helper is busy with something else rather than taking my car to the Car Wash. But i never allow them to get inside of my car. I always pay upfront, and my car is always washed..
as Ivanovna said, shit happenes.. but hey thanks for warning us..
