AT THE CAR WASH
I hardly ever get gas here, but it's my go-to when my auto needs a shower.
-Join the Terrible Herbst Car Wash Club and your 10th wash is free plus a free car wash on your birthday. Actually, I don't know if that's the official name of the club, but it may be close; the attendant can give you a form to fill out so they can keep track of how many washes you've had so far. Your receipt will tell you how many to go before your free one.
-I usually get the $8 Ultimate Express: "Soft Cloth Wash, Foam Bath, Triple Foam Polish, Clear Coat Protectant, Wheel Brightener, Spot-Free Rinse"
-Unlimited free use of the vacuums in the drying areas. Yes, this is the kind of place where you get out, dry the car yourself, and vacuum the car yourself. Don't be so lazy. That being said...
-If you pull up to the oil change place and ask nicely, the guys there will put air in your tires for free. I tip them $1.00 for saving me the trouble of getting out of my car and doing it myself, because I am too lazy to do that part.
-Voila! A clean car is a happy car. Just hope you didn't make the rain gods angry in the process.
