So, after failing at Walmart (The only phones in the store are at the different department desks where there are always people. I only succeeded once in the gun section, but after answering and messing with the guy employees were quickly scanning the area) I decided to go to target.
Now, the extension for the floor intercom at my target is 52#, which I'm fairly sure it is at all targets. (I even confirmed this by calling up the target in-store operator and asking her, pretending to be an employee)
Unfortunately, every time I dialed it from one of those red phones, I wouldn't hear anything in the earpiece except for a single click, and all you could hear over the intercom was what sounded like someone hanging up a phone. Also, this didn't happen when you first dialed 52#, it always happened after mashing either 52# or just 52 or just #, because nothing was happening. You would hear a "click" on the intercom, but even if I continuously blew into the mouthpiece/rubbed it to see if it would play over the intercom and it never did, before or after the click.
Was this an employee/the in-store operator just hanging up my intercom call whenever I called, or am I just doing it wrong?
