Generous tip?

As I was turned down my plan to offer my staff a reward for all the pains they have gone through these two months, all I could do is use my private money as the bureau chief to show my appreciation for their services...

Going to a restaurant serving "Caspian" food!

starters...

mahi (fish) my wife had!

and the kyabab I had!

dessert!

This is always my way of showing appreciation to them, but maybe it would only be a small tip for them... I'm trying to make it generous as possible... natural as possible... humble as possible... and hope they would understand I'm happy for their performances... though my bosses in Tokyo wouldn't care at all...
