I love to give compliments, I think it is a wonderful thing to do.
Yesterday, I returned a shirt bought for me that was too big, and the customer service lady (probably mid-forties) told me that returns from Christmas ended at the end of January, but she would put it through for me.
I told her she was very kind, and smiled at her.
She said that if I had not come in, I would have missed the chance of seeing her, and I agreed that would have been a serious loss.
I then said that if I was thirty years younger, and better looking and single, I would wink at her ... and then said I would wink anyway, which I did, and she blushed!
The trick is to quit while you are ahead!
