Realize the importance of your customers. Love them like they are your first love.
Learn to live with their shortcomings, bad temper and bad moods. Love them unconditionally and be ready to offer them everything you have. That’s what you would have done or would want to do for your first love – isn’t it?
What follows is similar as well. Learn to nurture that relationship. Go through ups and downs of it but don’t break it, try to fix it.
It would be a win win situation for both of you, always.
