How to politely ask the boss for the money he owes you?

You see, he is usually alone. If he is generous to others, or you didn't remind him this time, you should remind him at once. If the boss is always stingy and selfish and often borrows money from others, then don't be generous to such people. If you owe money, you should pay it back. You really shouldn't be polite to him after such a long delay.
