Stop in for a cup of coffee

So not car related but is mechanical! One of my men just purchased a brand new 2020 Harley. I saw it in parking lot first thing this morning and did what any self respecting old school biker would do and dumped some oil under it. I came in and never said a word, he has been showing it to everybody and so I noticed he had moved the bike over a spot, trying to ensure it was not his bike leaving the puddle of oil under it. Yep, I went and did it again. I then baited one of my maint men to having the guy show him his new bike. The proud owner is losing his mind as we speak! New bike less than twenty miles on it blah blah blah. He is having a total melt down. My moral dilemma is do I let him stress all night or confess before he goes home!
Please tell Em.......
