Unfortunately, I didn't write down the date. It was awhile back. They seemed none the worse for wear, because when the truck exited the blower area, they jumped out, grabbed towels from inside the truck, dried themselves off, got back in the truck and it drove away. Our wash is unattended, but I just happened to be watching the video that we have streaming into the kitchen TV. Lucky for them, they bought the cheap wash which is just Wash, Rinse & Dry. Wonder what they would have looked and felt like with Triple Foam, Sealer, Protectant, Drying Agent etc. all over them.
