4K a day to check emails, reply to some of them, make a few
phone calls, read the newspapers to keep updated on news, maybe
surf internet to guage public sentiment.

You forgot about golf sessions to entertain other Ministers,

I wonder why nobody mentioned that Goh had master tailors
from Ermenegildo Zegna specially flown in from Italy to custom make
his suits. I wonder if that's a perk that comes from office. I
betcha any unpronounceable Italian sounding brand is going to be
expensive.
