Back when I was absolutely young I used to go to the mall with our friends.
The two of us used to like hanging out in addition to shopping.
The mall in our local section at the time was unlike any general mall in the country as far as I knew. They had these absolutely lavish in addition to lovely water fountains that went so high up in the air. Then they had a absolutely good central HVAC set up too. The air vents were both in the floors in addition to in the walls. At that time seeing air vents in the floors was pretty unusual, however what was even more unproper was the fact that if you looked inside those air vents of the central HVAC plan you would see pennies down there! People used to throw pennies in the fountain to make a wish… But they were also throwing pennies down the air vents that were in the floors! This was pretty messed up when I think about it now as a full grown adult. The pennies down in those air vents could have eventually caused some drastic disfigure to their central HVAC plan unit! I would imagine that it was most likely a commercial HVAC unit because of how large this mall was. A general HVAC plan would have never covered this entire building, but unless they had several central HVAC units. And I do not think they did.
