What "Thank You" Can Do For You

I have made a major effort recently to say thank you to any and everyone who does something for me especially at restaurants, stores, etc.  I have found out that a simple smile and thank you really improves the treatment you receive and seems to make some people's day.  It is really easy but you have to do it consistently so it becomes common for you and something you intend.  I have had waitresses completely turn around their attitude, drive through staff not know what to say when I thank them after they take my order and sales people remind me of discounts.  Just a thought, maybe if we all did this - just thank those who do things for us - we might find life easier and all be more happy.  So say thank you and smile!  It will not only be appreciated but smiling is considered an exercise!
