Me dropping off my car for an oil change, tire rotation and car wash: "So, how long do you think this will take?"
Oil change employee: "Probably 45 minutes or an hour."
Me picking up my car two hours later: ***sweaty scowl***
Just be realistic with your time estimates, okay guys? That way your customers can plan accordingly.
Under promise and over deliver; THAT'S the secret to dazzling your customers. PS: If he'd told me it'll be 2 and a half hours to do my car and then I'd gotten my car in 2 hours, I'd be writing my review in a totally different frame of mind.
