The Sims 4: Pizza Delivery Guy Doesn't Know Outside From Inside

First

There are 2 doors in my house: front and back.

Some visitors come through back door, walk to the front door and knock it from inside.

Second

My house has a balcony. When I select to invite my visitors to house my sim first goes to balcony, waves to visitor then he/she goes outside and do the actual greeting.

It would be awesome if sims could invite visitors just by going out to balcony especially from the second floor.
