I was picking up dinner tonight from a local restaurant - there were two hostesses, a younger and older (in her 40s). After I got the food , as I was opening the door and walking out I heard the older girl yell "bye handsome guy!". Not sure how to read this, can't tell if I should read that as sarcasm or genuine interest. Not used to this type of thing happening , that's why I'm asking- what do you guys think ?
