u cannot act the way you like and just what you feel like based on your moods especially when you ar eout dealing with people ahammed. your feelings are never an excuse for your actions epecially at the workplace, your clients or customers are not your family or relatives who will understand, they expect the better of you even when you are feeling whatever inside. if he has a probelm and thinks he can't handle customers well that time then better take a break first. i'm with you ayetha.
