You can open or replace this fake ceiling square by square as behind it you may find some electrical stuff that sometimes needs to be repaired. It’s also probably cheaper.
It’s kind of the same as the floor in data centers. If you’ve been in one, the floor is a fake floor made of square sort of plastic tiles. Below that you have the cold air that goes into the servers, AC and DC power, fire and water detectors, cables road etc. You need an easy access to those fake floors or ceiling for maintenance.
Pet me like one of your French girls or else I will take all your food and money.
