Good thing it wasn't to your house!

If you do not know for a fact that someone actually lives in the building, you do not let them in. It really IS just that easy. Once every week or two, someone buzzes my apartment and asks me to let them in to visit their friend in another apartment. This conversation is almost always exactly the same, though with different people each and every time: "I'm here to see Henry." "Then push Henry's buzzer." "His buzzer's broken." "Then call him on the phone and tell him to let you in." "I don't have his phone number." "You're his good friend, but you don't have his phone number? You can't buzz him, and you can't call him, but you're certain that he's home right this minute, so I should just let you in? No. Not gonna happen." Which would you rather be: the guy who's always nice and helpful and polite, or the guy who opened the door and helped the burglar who robbed several apartments?

Hookers look like normal people too, everyone. They aren't always dressed scantily or whatever. Working at a hotel, lots of prostitutes would wear hoodies and jeans/sweats when they aren't soliciting people. If you don't know the resident and someone just acts like they're coming home normally, it's not unreasonable to just let her by or whatever. he's a maintenance guy, not a security guard. sorry, OP and Husband

oh I'm sorry sir, I accidentally locked my keys in my house can you open up XXX for me? That's how he "accidentally" let her in. Maintenance aren't expected to know all tenants by face.

Sorry, that sucks. But I wouldn't feel safe if he was my maintenance guy. Maintenance should never, ever, let someone in to an apartment. They don't know who lives there, that's so dangerous to your life and your stuff! I actually had this happen to me. I came home to my door unlocked and a letter on my table from my psycho family member. Maintenance was in the building and opened the door for them as they were "family." No only was my door left unlocked all day after that, but I was freaked out. I have a restraining order against this family member for good reason. I couldn't sleep there that night, and for days kept re-checking all the closets, under the beds etc. Super scary, and a not at all acceptable breach of security and trust.

Hope it wasn't your house

I was wondering how long it took for you to notice.

Not positive, but I believe the OP is insinuating that someone blamed the maintenance man for there being a hooked in their room when they got caught by there significant other. Not that he let one in...

How tf do you "accidentally" let in a hooker

I'm a commercial and condo maintenance worker. Believe it or not, it isn't hard to use us to get into a building. Some electronic doors stay unlocked for 30 or so seconds after the code is used, or the door gets propped open, or a tenant starts screaming to be let in... Humans are a weak point in any security system whether or not they mean to be.
