How Horrible of a person am i?

I have had this running through my head for 2 days. So i work at a movie theatre you know so i stumble across an iphone (I already have the white iphone4) under a seat now im supposed to return this( First iphone ive ever found big piece of technology) and that's what i usually do ive returned 42$ cause i'm not dishonest! So 1 of my coworkers sas he wants it he takes it from my hand and puts 4 lousy dollars in my pocket and tells me i didnt see nothing. Im like okay and i let it go like this till i get off now im regretting and wishing i could go back in time and return this to the manager cause i know the customer came back for this who just leaves an iphone? I cant say nothing cause i'll get fired either and i feel like going to a priest so he can repent my sin I was stupid i know this wasnt even my friend just a co worker man do i feel dumb. I was reliving that moment as i was typing this!
