A high value customer has just lost a large amount of money on a roulette table and throws a glass of water over the dealer. What would you do?

Smile :(( Smile :(( Smile :(( Smile :(( Smile :(( Smile :(( Smile :(( Smile :(( 

I suggest to replace the table dealer

Here I am trying to smiled at him . And sorting out the problem. I understand this and I did the work that he has done is not suitable because it is affecting the institution.

It must respect the place

No undue

First, respect of treatment and service

Clean up and stay back. the customer is having a trouble and that should be understood. however a charge may apply.

Agree on experts answers, Thanks for your invitation.

As a Manager, I will ask him to come with me in order to get some relax mode in my office, and ask the water for some "iced lemon drink" to him !!!

You can have them step aside & create a pleasant dialogue with them to help them to get back on truck. You need to make them understand politely that a "game is a game", it is a subject of confrontation, anger, joy & mixed feelings- a matter of chances- you can either win or loose but loosing isn't always the end of everything. You also need to politely make them understand the need to behave maturely & professional & to ultimately comfort them & motivate them to pick up themselves & start over again stronger next time

I will, smile at him, and try to solve the problem, and assure him, that , if i find any were , in the premises, i will , inform you.

The most dissatisfied customer is the model of the Best Institution of my learning.

Who am I - the dealer or the manager? :)
