Speak gently to him and don’t be too confrontational.
You see covetousness? Flee from it.
Never brag about what you don’t own.
Hellooooooo! This job doesn’t make him a lesser being.
Don’t be rude. You ordered a ride, not a slave.
It’s your money but that doesn’t make you superior.
It’s his service too. You can look elsewhere.
Posing in the owner’s corner doesn’t make you his boss.
The service he is rendering doesn’t make him illiterate.
In fact, he is most likely more professional and literate than you.
If he gets nosy, politely correct him.
Don’t call him your cabman if that makes you feel superior.
Being nice won’t hurt.
