Disregard the posted hours folks. If they say they close at 5PM don't think that you can come in 30 minutes or an hour before closing time and receive simple service like many places. Yes, they're very "polite" about refusing service, but it will be a service refusal nonetheless. I'll be heading back to Jiffy Lube from now on. They're a little pricier, but I have never left without having received excellent, attentive service.
