Why not

Order sent, I go welcome a couple of girl into the next tattami. Being their first time, I gladly explain them the menu.

To the bar, I grab the bottle of sake and 2 cup. As soon as I enter the black man's tattami, I swiftly serve him is alcool.

"Drink with me, you do know I am the VIP here." He said to me.

Seeing this a way to make up to my customer, I've replied ; "Yes sir..."

As the night goes on, the VIP, kept ordering bottles after bottles.
