Please Do Not Ship The Staff

I’m a service technician and I’ve got a new trainee riding with me. I’m male and the trainee is female. We finish our work, and the trainee asks if she can get the key so she can warm up the van while I’m finishing up with the customer. It’s cold and snowing out, so it sounds good to me. I reach into my pocket but accidentally pull out the wrong key ring.

Me: “No, I’m not giving you my house key.”

Trainee: “Oh, come on! I thought we were friends.”

Customer: “Or more than friends?”

Me & Trainee: “…?”

Me: “Let me just get a signature on the ticket and we’re good to go.”

Normally, I’d ask if the customer had any questions about the service, but I was a bit too creeped out, so I gathered my tools, politely said goodbye, and got out of there.
