The respiratory system compares to our bell boys because the respiratory brings needed nutrients to different parts of the body. The Cell Towers' bell boys bring all of your luggage to any part of the hotel you are located in. We are also pleased to say that our bell boys can now bring your luggage to your room EVEN faster! We know how important your luggage is to you, exactly how oxygen is vital to the body's cells so The Cell Towers made it their mission to have a faster delivery. Our bell boys are using the latest in Bell Boy technology, the Lung Cart to bring your bags to wherever you are faster than your lungs van bring in oxygen.
