Obviously they drive a car, but what else?
In movies you always see rich guys having chauffeurs, but the rich people usually have maids and other servants. So what do chauffeurs do when NOT driving the rich people around?
I assume the chauffeur would be in charge of all car maintenance as well, right?
The ads I’ve seen for private chauffeurs in Spain always require him to be a mechanic, so he isn’t just supposed to take the car down to the garage when it breaks but actually be able to fix minor things and argue with the garage’s mechanics.
There are also ads for “married couple” where she’s to be the homemaker and he to perform general maintenance and chauffeur the owners when they’re in at vacation homes (I’m reasonably sure those ads are illegal on several counts of “discriminatory practices”, but what the law says and what gets done can be worlds apart).
When I was in college, the house next to my dorm was owned by a Count whose chauffeur seemed to spend a lot of time either sitting in the big car or leaning against it, waiting for the boss.
What do pilots do when not piloting? What do cooks do when not cooking? They do routine maintenance and probably keep some kind of log or records. And they wait to be needed.
I used to have a neighbor that had a chauffeur plus some other full-time help. She was some kind of older heiress who was mentally disabled so you she needed help for everything. The chauffeur drove her around in a black Lincoln Town Car but it isn’t like they drove around all that much. He was usually out in the driveway polishing the car. He washed and polished the car every single day as far I could tell. I doubt he made all that much money but it seemed like an easy, low-stress job.
Why? My grandparents had a couple, it relates to the size and arrangement of living quarters provided. If there is only a single bedroom and sitting room, you can’t put a non married couple in [or a non significant other couple] Come to think of it, so did my great aunt, and my great grandfather [the servants rooms at the perry house were a bedroom and a sitting room, and a 10x10 nook off the kitchen with a closet for coats and outside gear, and in pictures of it from the very early 1900s a rather comfortable looking table and chairs for meals.]
I think in the early twentieth century, cars were unreliable enough that it was necessary for a chauffeur to be a part-time mechanic. Now, cars are reliable enough that it’s not necessary, so many wealthy people drive themselves around.
But pilots have schedules, they know what and when they will be flying in advance. Sure the chauffeur probably has scheduled drives, but I was thinking they must do something in between times.
It’s like firemen. They don’t go out on calls all the time, but they have activities they have to do, when they’re not fighting fires.
Chauff? 
IANAC, but as I understand it the chauffeur is pretty much in charge of the car(s). Maintenance, cleaning, keeping the gas tank full, keeping the bar in back stocked. In addition, the job also includes some valet services, such as running errands, carrying bags, and so forth.
I guess there are no really rich people on the SD Message board that have a full staff of servant and can tell us first hand 
A chauffeur might also end up being in charge of the employer’s schedule - telling him or her that “if you want to be at point X at 10:00 we need to leave at 8,” or “You’re expected at the countessa’s ball at 7 - we must leave shortly” and also might be assigned to pick up guests of the employer at the train station or airport.
Pilots for airlines have scheduled flying.
Pilots for rich folks fly on demand/whim of the boss, much like the chauffeur. Arrangements vary wildly, but a typical private jet pilot might have to be available at an hour or two’s notice, and handle flight planning, making catering arrangements, stocking the aircraft, and other airplane dispatch functions.
Down time could include anything from light office work related to the airplane, such as maintenance record-keeping and compliance, to maintaining the appearance of the hanger and/or aircraft. I’ve even seen jobs advertised that included waxing the boss’ car as a job requirement. Some guys want to buy a multi-million dollar plane, then get all worked up about paying salary for a pilot on days not flying. Generally, the more duties required that are not related to piloting the plane, the less desirable the job.
He chauffs.
Official duties for Britney Spears chauffeur
Vacuum up the odd white powder on the carpet
Sponge off the sticky seats (that girl needs to buy some underwear!)
Shampoo carpets occasionally to remove alcohol smell from vomit
Keep baseball bat in front seat to fight off obsessed fans
Be prepared with assortment of brightly colored condoms whenever the lady of the house gets horny.
He/she (I’ll stick with he for ease) might be the chauffeur for the family rather than one person. Also, if he’s driving Richie Rich a long way and then back home again, he has to hang around for hours waiting or drive all the way back home and the back out again. Granted, hanging around waiting isn’t hard work, but it’s not like he can pick up other work in that time (unless he wants to get fired).

At least in China, this and errands in general are correct.
Sometimes, the lady of the house.
Some super rich or influential people have armored limos with specially trained chauffeurs. They complete several high performance driving courses designed to reduce the risk of kidnap or assignation. They can do bootleg U-turns on a dime. Crash through roadblocks. Evade pursing vehicles etc. Very important training in places like Italy where kidnapping is a thriving enterprise.
I recall a nasty assassination a few years ago. They shot a missile into the limo. Went through the armor like butter. Killed the bodyguards, the rich guy, chauffeur etc.
I used to know a lot of these types of pilots when I lived in the Keys with really rich people. I wasn’t one of them, the difference is they don’t employ ONE pilot for the sole purpose. They hire any number of private pilots from a list. I worked with a girl, who was a such a private pilot, who also worked at the hotel, answering the phone, “cause it was so much fun…” (Talk about being rich and goofy)
Anyway she had a list of clients she’d fly from Marathon to Miami, Key West, Naples, Palm Beach. The difference, she didn’t work for ONE person. That changes the equation a lot.
