Always be responsible for your job. Be there on time. Always be with patients when there. For ex: I'm talking in the phone and a patient comes with a huge hurry, and i tell him "Oh wait don't you see I'm on the phone." Suddenly the Sr or ma'am  leave you just lost there. They might not ever go to that store any more.So you always need to be with patients always be there in time  or be there earlier.
