I can remember back in the day I used to go to a mall where I was growing up and there were these huge fountains where everyone used to throw pennies into to make a wish. One time I remember that somehow some pennies had got into the heating and air conditioning system’s air vents which were in the ground right by the fountains! They had to call some local heating and air conditioning company to send out a team of certified heating and air conditioning specialists to take the air vents apart and get the pennies out of there before it damaged the commercial heating and air conditioning system unit they had in the mall. It was very interesting to say the least and I was lucky enough to be there at the time to witness the whole process. They eventually took away the fountains because of what it was doing to the commercial heating and air conditioning system and then eventually like many other malls, today it is dead. It no longer exists and was torn down and became a parking lot about a decade ago. Sad really. But I will always have the memories of that day. These days something like that would never happen because heating and air conditioning technology has changed so much, there would never be air vents in the floor of a mall with a commercial heating and air conditioning system unit. Times have changed that much and time moves on every single day of our lives.
