Mold in stores, restaurants, buildings.

Have you ever walked into a building and looked at the ceiling.  I do every time.  I can't tell you the amount of ceilings with water damage from HVAC systems and condensation in the stores I have been to.  Look up, if you see water damage on the ceiling tell the store manager.  I have been do Dollar Stores, and discount stores to find that they do not take care of their stores, they must not care about their people even enough to change out the moldy ceiling tiles. Its disgusting.  If you go to a restaurant and the ceiling is black, RUN!  That means they could be hiding the black mold when they have water leaks on their ceilings, after all its all about the bottom line and nobody owning a business wants any extra expenses.   A little maintenance and a lot of problems could be avoided, for example, changing air filters regularly, cleaning the HVAC coils regularly.  Checking for water leaks regularly, and not just painting over the problem.  I have seen that done so many times.  Be aware, be smart and do some research.  Nothing is perfect, but if you can avoid mold exposure do it whenever you can.
