Smile- the cheapest facelift

Someone told me to smile and never to frown because you would never know whose life will be brighten up with that simple smile.I asked him .,'Oh really?'.He smiled to me and answered, 'Absolutely, yours have brightened up mine.Plus why would those uncles fall for you?."I laughed as he referred the uncles as the hotel guests who always look for me whenever they stay at my work place.The identity of this person?.Let it be a secret for now.Being in hotel industry for 7 years, a smile is an absolute weapon for hoteliers to have.It was hard for me during my first year in the industry but bit by bit it became a part of me.
