Both Are very Important , so you have to give the same attention to both Customer And employer.
If you do not give your attention to your employer so he will FIRE you ,
And if you don't give attention to the customer then also your employer will FIRE you.
But front of your employer give your all attention to the customer , and when you dont have work then give your employer an attention.
Hope my Answer will help you :)
