Zoning out... in the supermarket?

depending on where you live it might be the air conditioning or heating system.I would approach the manager about this, it might be something in the ventilation that others have not made the connection.I am sure you do not want the elderly to develop problems or children to develop problems.The manager might have to get the entire system cleaned out, which might be maddening but in the long run I am sure the store does not want a lawsuit So approach the manager and save a few lives.Good luck
