base on ifomation from my fren tat currently still working at GH, each floor will has its own cooking room tat contain a water heater+cooler machine,
but need 2 make sure it is functioning at tat time.
all staff are not allowed to enter any hotel compound, at there have cctv, if u r new then i think can go in a few times becoz de security still cant remember new staff face, but if unluckily get catched by security, then they will warn about 1 or 2 times if get catch again then they will say bye bye with u
