Get you Car Cleaned at Thasevi Jalan Kayu Prata Restaurant

Something interesting caught my eye today.
I was hungry for some prata, so went down to Thasevi - Famous Jalan Kayu prata for lunch.
After ordering my food etc i took a seat.

Looking around, i noticed a BMW pull into the front lot of the shop.
Now comes the interesting part.

Out came an Indian man ( noticeably well dressed - Probably the Boss ) . He shut the door and approached one of the staff of the "restaurant" and signaled to him to clean his car!

The staff ( who was a young Chinese man ) then, picked up a cloth from the nearby table and began wiping the BMW!

Now, i'm not sure if it's in the staff's contract or not, but something doesn't feel right.

1) Is it hygienic for this to be done? Cloth wipe Car - Cloth Wipe tables? Would you use your car sponge to clean your dinner table ?

2) Maybe i'm thinking too much, but why does the Chinese guy have to do the cleaning? There're so many other staff standing around - and he picks this guy. Unless it's his job - i'd say it's racism. The rest of the staff just stood around and did nothing lol

3) Is this abusing your staff? To the best of my knowledge :
Waiter - Clears Tables , Serves Food, Cleans restaurant at end of day.
Car Washer - Wash Cars , Polish Cars , Cleans Cars
Dish Washer - Wash Dishes & Culinary
So if this boss decides to drive his entire fleet of cars to the restaurant, this guy's gotta clean them all up?

Oh well, i know i won't be eating here in a long time.
