The OP's question is perplexing. There are thousands of people each day that smile and are friendly to CM's (and do it not even expecting anything), yet the OP seems to feel they're more entitled to something for free because they are going to smile ? I have to admit, this cracks me up.
I am sorry if a simple question caused you to become preplexed. Laugh all you wish if that makes you feel cool or better. As I mentioned, I travel a great deal for work and I constantly get free upgrades in my rooms at the hotels and resorts I stay at simply by asking, yes, that is right.
All I did was ask a simple questions as I do not visit this site or Diseny as frequently as many on here.
For those with the helpful and insighful replies, my family and I thank you...
