Influence of Guest Relation Officer (guest service) on the operation of Front office department?

As a Guest Relation Officer, we are considered as the front liners of the business establishment, the hotel itself. We should always be the presentable, and knowledgeable about our products offered to our guest. And at the same time we are the "go to" individuals for our guests if they need something important to us, such as reconfirmation/re-booking of their flights, calling their taxis,  etc. We should be the one make their stay memorable in one specific hotel.
