Say “Please” And “Thank You”
Follow up every request, inquiry or reply with “please” or “thank you.” This task is easier for some more than others. Generally, people are more inclined to help those who seem appreciative or grateful for their help. Letting the people around you know that you recognize their efforts and that you are thankful (even when inside you may be cursing them to hell) can go a long way. So follow up those requests with a “please” and/or a “thank you” until it becomes natural.
