Theres rough idle, and theres rough idle

When I call O Riley's the first thing I say is what kind of car are we working on today? LOL they always laugh...
And of course just before they're done helping me I'll let them know they're open till 10 every night! LOL you know before they tell me that at the end of the call...
I'm sure it's just as painful for them and it's all policy...
