The woman taking my order at a fast-food restaurant was about 25.

She was attractive and had a bubbly personality and a warm smile.

Even though I'm 45, I felt there was chemistry between us.

Before I walked away from the counter to sit down, we made eye contact and again exchanged smiles.

Eating my burger, I glanced at my receipt¹. It turned out she had given me the senior-citizen discount.
