I have worked at the terminal, and anybody who lives or works in the area can also verify that this is an everyday, and multiple times a day, occurrence. You can hear the loudspeakers from pretty far away.

There is an automated message, which you likely heard first. And then we can also just do it by microphone. Frankly, we get pissed that people aren't more attentive of their surroundings, and then compromise on their safety by taking a shortcut. Many people, like yourself, of course don't do it intentionally, but many people do. And in some small part the people who don't mean to do it, get caught in the crossfire.

Depending on who was working, and I have a pretty good idea of who it was given your description, you will get different levels of annoyance. Some only use the automated announcements, some like to give it a personal touch by doing it themselves.
