Might As Well Be Using Snake Oil

I work in the automotive department of a store, and I know absolutely nothing about cars. The only reason I got the job was because I applied for the wrong one.

A guy comes up to me holding a bottle of chainsaw oil.

Customer: “Is this the same as automotive oil?”

Me: “I don’t think so, but I’m not 100% sure. May I get a coworker who would know? He used to own his own car shop.”

Customer: *Ranting.* “How stupid! You should obviously know these things! They’re 100% the same thing! I’m in the car business, and you should be thanking me on the free education!”

With that, he storms off. I ask my coworker later and apparently, they are definitely not the same, and putting chainsaw oil in your car can seriously screw up the engine. I wonder if he’ll be back…
