This just happened today and was one of the more "cool" things that's happened in a while...
Walked into Nordstrom with a friend... I needed a sunglass case for a pair of pretty expensive sunglasses... ask the sales guy if he has any hardshell cases to fit these glasses... he says wait a sec, walks to the back counter, looks in some drawers, then hands me a brand-new case... I ask him how much, he says don't worry, it's on me?!? WTF! I'm like no, I really should pay for it, he says he'll take care of it? So, I go thanks... (my friend and I are more worried about being stopped by security at this point, but luckily she was able to close her gaping mouth fast enough at this point and walk out with me)... as I'm leaving the store I opened the case, and the sales guy stuck his business card inside, and wrote "Call me and his # on the back"... This was one of the better things that's happened.
The guy was about my age and cute too. 😀
