Istana is looking for a Butler

I came across this rare job posting.

Do you have:

• Singapore Citizen
• GCE 'N' level
• Professional Certificate in Food and Beverage Service in Professional Institution/NITEC; and
• Two years relevant working experience, eg Assistant Restaurant Manager, Restaurant Captain?

Then you can apply to be a Senior Butler at the Istana and expect to be paid a gross monthly salary between $1,880 - $2,180.

Don't you wonder about what such rare jobs entail? What kind of people they meet? What kind of work stress there is? What kind of encounters they would have?
