Self-Service Car Wash

Today was my day off so I had a chance of going to my favorite self-service car wash. 


One benefit of having a different day off than the majority of the working population (whose day off seems to always coincide with the weekends), is that the car washes are usually empty. I can just go inside, and start washing my car (eliminating the waiting time). 


All in all, it saved me 7 bucks (as compared to an automatic car wash. And I completed it in just 20 minutes.

The only regret I had though was I still do not know how to maximize my investment so that I can go over all the car wash features  (I cannot figure out a way how to use the Rainx feature, for example).


 
To recap :

Savings : 7 bucks        Time Spent : 20 minutes
