All employees are representatives of the organization they work for. If you are a receptionist or waiter/waitress, you are the representative and face of the organization you work for. This position can either make or break an organization’s customer base.
As a receptionist, it is pertinent to have good manners and show courtesy to customers. When you are on the phone with a customer and a walk-in customer stands in front of you while you are still on the phone, it is display of professionalism, good manners and show of courtesy when you make eye contact combined with signaling of hand that, you will be with them in a moment.
Not doing this, can be likened to someone with very bad manners and without character, and this can make the customer to not repeat the call, mark you as one of these folks without character, and finally tell everyone they meet about you.
That’s not what you want to project. Correct?
