We place a RIFD sticker on your windshield that is scanned at the entrance's automated teller. Upon each visit, you will be prompted with an option to upgrade your wash. Simply pay the difference for that day's upgrade without changing the amount you pay monthly. It's great for those times when you need a little "extra". If you do not wish to upgrade, no problem, simply press "No Thanks, Pay Now" with no upgrade. Restrictions apply, see Attendant for details.
