Yah, the car wash for my previous service also nood that good, told the SA and he ask the uncle to wash again. I pitty the uncle, one person wash so many car.
Think again, there is so many car doing servicing on any day. If they use machine wash, prepare to get scratch. If they use hand wash, The first car of the day may be much cleaner than the last car, after all we are human. Dont think they have a car washing team to make sure all car is clean inside out. I even wonder did they just jet spray water then wipe off for every car, coz I had a patch of wax which I forgot to buff off before the servicing and it was still there after the second washing. So in future I will ask them just jet spay the tyre area and under car will do.
