It was so funny to think that when you are on sales job you always have to "SMILE" no matter what. Yes, it's hard for me to comprehend that before but after I landed on one sales job, SMILE is part of your life.
Well, maybe the environment is contagious that makes you SMILE so easy. The bosses are nice too and they are always smiling. Even when I'm off from work and just browsing at stores, when I saw people I always give a warm smile at them. I wish they won't think I'm weird or perv hahahahaha.
