Inspired by Lauren's "Hotel Giveaway" thread, I want to share a restaurant giveaway I witnessed.
My dinner partner and I were seated next to a table where a gentleman sat alone. When his date arrived, he stood up, gave her a kiss on the cheek and handed her a gift bag. She smiled, accepted it and sat down.
She didn't look inside the bag the entire time we were there.
Now the only reason a person doesn't look inside a gift bag is because she already knows what's inside.
Even if I can feel that the bag is too light to have a real gift, I peek inside (with my eyes, no hands) and say "Oh my favorite fragrance! You're so sweet," just as a little realistic detail.
