The management want to safe electricity is it, why lights not on ( 2nd pic ). What about air-cond, was it on as usual ?

2 weeks ago went to IDCC Shah Alam, eventhough it isn't like a conventional mall, but for home & decor, less than 10 shops still open, the whole mall less than 20 people including the staff. Most shops, the staff also went missing. Felt hot because air-cond probably only 10% on.
