Here is your third clue:

“Dirty looks and concerned glares are all I am getting

As this Kwik Trip Station is the next location I’m vetting

I was here a week prior to fill up my boat

When the corner of the gas pump got stuck on my coat

My coat was where the medallion was, I thought it may have dropped out

Though I also could have lost it at Copeland Park, by the dugout

I need to find it! The people are waiting!

Otherwise my boss is going to start with the castrating.”
