 Directors were very happy that Omar Sharif (qv) accepted the role  of British agent, so they invited him to a dinner after he completed  his scenes. Sharif accepted the invitation, and a very special  dinner was prepared for him. But he didnt show up, and soon it was  found out he already left England. When he was later asked why he  didnt come, he replied, "Its a tradition in my culture not to  refuse any offer. Example: someone offers you a drink, you should  accept it even though you wont drink it." Unaware, ZAZ enjoyed a  very expensive dinner, all by themselves.
