My ex-colleague was a driver. He drove many VIPs (I shall not name them) both foreign and locals. If your boss is good, you are lucky. If he is bad, you will go hungry for hours on standby, while he milked his mistresses....hahaha. You get the chance to see many faces, celebrities and important people and their secrets "activities". Anyway, it all counts on luck and you will be rewarded generously but not all wealthy people are generous if you are not their gals, and even their gals will look down on you.
Let's just say, you are paid to do your job.
