The best thing to do after having to see customers fighting
is to be able to go the scene immediately and to separate the customers that
are fighting and calm them down, if they are many in numbers, it is best to
call for back-up, so that there will be someone to help you in the situation.
After doing so, it is best to ask the customers the cause of the problem and
let them have the problem to be talked out in a more private area to prevent
other customers from being bothered.
