I went to Jiffy Lube exactly once. Or at least i tried to.
Usually i go to Easy Lube up on W Washington St. I pull in, they change my oil, i go on my way. Pulled into Jiffy Lube and they told he it would be an hour wait (only 1 other car in the bay) or i could make an appointment for Monday. (This was Sat.)
I went there because i had a coupon but it wasn't worth the hassle. Just drove up to Easy Lube and was on my way in about 20 minutes.
