self service car wash

I felt cheated! The total cost of cleaning my compact car came to 13 dollars. To be fair the car was quite dirty and I expected that all the sand an detritus would need extra time on the vacuum. What i did not expect how poor the vacuum was of 2 different machines. Sucking up sand was a challenge. The washer bay was fine and had the convenience of credit card payment which i would recommend using cash since the automated thief charged me $10.00 for 3 minutes despite the advertised 3 dollars. I will not return and I am considering disputing the cc charge.
