 A mechanic, because if somebody comes into you and says, Chris, I need my car worked on. I think it's vapor lock. Well, if you know what vapor lock is, you can say, we'll take a look at your car, see what it is. But it's probably not that because this is a modern car with pressurized system and it shouldn't have that occur. But if you don't know what vapor lock is, you might be going, oh, I got to look this up.
