Things that would help you be efficient are as follows:
1. For new expensive prescriptions always let them know how pricy is that even before pulling from waiting bin; ask them if they are aware of the high copay. Ask a senior tech to let you do Find Insurance under his or her supervision. Ask your colleagues to show you updating insurance and how to reprint leaflet.
2. Always be polite and for the rudest customers just say let me ask my manager help you regarding your concerns. Do not let the angry people put you in a trap they have designed for you. Always be super professional.
3. Ask your supervisor to provide you with a list of short cuts for fast data entry.
4. Keep track of all your TR7 training to make sure you are paid on time.
