Considering this a quick car wash automated, I think they do a good job and are friendly

When there is a young person wiping vehicles down at the exit I can not help but notice how cheerful, smiling and are working at it. I always give a tip, to that young person I hope others do also. Let’s encourage good work and their smile while working

I only use the car wash. Not a believer in that type of engine care, just personal choice
