Who took the last donut from the break room?

Detective Pux here, and I've been tasked with solving the great mystery of the break room donut thief. The situation is dire, folks. A delicious pastry has gone missing and we need to find out who is responsible. I'll put on my thinking cap and get to the bottom of this confectionery conundrum.

First, let's examine the facts. The donut in question was the last one in the break room. It was a scrumptious looking glazed donut with sprinkles. It was left on the counter for all to enjoy, but alas, it was not meant to be.

Now, the question is, who took it? We have several suspects in mind. There's Dave from accounting, who has been known to have a sweet tooth. There's also Sally from HR, who has been on a diet but might have given into temptation. And then there's Bob from marketing, who always seems to be sneaking around the break room.

To solve this mystery, I'll need to use my detective skills. First, I'll check for any crumbs or evidence left behind. Ah-ha! I see some crumbs on the counter. It looks like the thief might have been in a hurry and dropped some evidence. I'll collect these and send them to the lab for analysis.

Next, I'll need to conduct some interviews. I'll start with Dave from accounting. Dave, have you seen the last donut?

Dave: No, Detective Pux. I haven't seen it.

Detective Pux: Are you sure? You have a reputation for having a sweet tooth.

Dave: I do love my sweets, but I swear I didn't take it.

Detective Pux: Okay, I'll take your word for it for now. Next, I'll talk to Sally from HR. Sally, have you seen the last donut?

Sally: Oh, Detective Pux, I'm on a diet. I didn't touch it.

Detective Pux: Hmm, okay. And finally, Bob from marketing. Bob, did you take the last donut?

Bob: What? No, Detective Pux. I was just getting a cup of coffee.

Detective Pux: Okay, okay. I believe you. But someone took the donut, and I'm going to get to the bottom of this.

Now, let's check in with the lab. They've analyzed the crumbs left behind and have made an interesting discovery. It turns out the crumbs are not from a glazed donut, but from a chocolate one. This changes everything!

I'll need to conduct more interviews now that we know the donut in question was not a glazed one. Let's start with Dave again.

Detective Pux: Dave, did you take a chocolate donut?

Dave: No, I didn't. I swear.

Detective Pux: Okay, okay. Let's move on to Sally. Sally, did you take a chocolate donut?

Sally: Detective Pux, I'm on a diet. I didn't take anything.

Detective Pux: Alright, alright. And finally, Bob. Did you take a chocolate donut?

Bob: No, Detective Pux. I swear. I was just getting a cup of coffee.

Detective Pux: Hmm. This is a tough one. We know the thief took a chocolate donut, but none of our suspects are admitting to taking it. What could have happened?

Suddenly, a lightbulb goes off in Detective Pux's head. He remembers that there's another department that shares the break room with his team. He heads over to the other department and finds out that one of their team members, Steve, had come in early that day and had eaten the last chocolate donut before anyone else arrived. Case closed!
