Snake skin in the ceiling

So I am sitting here at my desk minding my own business because it's a boring day and I have done everything I could do today work related. I get a page from upstairs from my general manager "hey Morbid??" and I sit there thinking to myself.. "just because I have snakes doesn't make me morbid... wtf" but I politely answered "yes sir?" and he replied "can you come upstairs to the conference room, I need to show you something" to which I immediately replied "is it a snake?! we have a snake?! I'm coming!!!!!!!!!!" and I sprint up the stairs... to find snake skin on the floor... they are replacing the ceiling tiles from where our roof used to leak and when they pulled down the old tiles they found rodent droppings and snake skin falling from above.. I took a couple of pictures. Too bad IDK what kinda snake it is... but anyway It's pretty cool... now they are all freaked out about a snake and it could be growing upstairs in the ceilings and wtf... and expect ME TO KNOW what kinda snake it is?? ahahaha.. I think the skin was approximately 16-20 inches long??... I took the snake skin and wrapped it around my bosses door handle to his office

The first picture looks like it had strips not bands or saddles, maybe a garter?

I dunno? It was just really interesting... I never thought about them being up in the ceiling tiles lol... but I guess anything is possible.

When I had a store we had not one but two black rat get in through the a/c. And not small one, they were both over 4 feeet.

Lol yikes. Im not so much scared as i am nervous for if it appears and they call pest control people
