Do you have $2?

This morning, I saw an older lady walk towards me. I moved my gear so she could sit next to me. She had a walking stick and was wrapped in a traditional silk sari-like robe. She smelt like old people and spices. .
She smiled. I smiled. Old lady thinks I'm a good person. Melted peanut butter and butter Spongebob shaped toast guilt factor - nil, Feel good factor - one.
Old lady keeps the smile. I keep the smile. Awkward.
Old lady asks "Do you have $2?" Smile intact.
What the douse?!
I gave her $1.50.
Old lady turns around, "Do you have $1?"
I felt rorted.
