What do you think of me calling the police on people holding the front door of my building open and smoking inside?
Why do they bother you so much?
They smoke and drink and it's not acceptable to me.
I'm sure that having annoying neighbors is frustrating for you, but it's usually a better idea to try to talk to disruptive people first before calling the police. Many people will try to be more accommodating if you ask them to be, but will be insulted if you immediately call the cops. Try to have a calm discussion with them.
No I'm just going to go upstairs and making a big deal about it.
While they shouldn't be smoking inside, I think it's best to just ask them politely first. The police are really busy with important matters like robbery, and you might be taking away those resources from some minor inconvenience.
