I checked out a couple library books for a man at our front desk. He picked up one of our free bookmarks that I ordered before the pandemic and have only put out for the public now. It has a picture of an herb.
"What herb is this?" The man asked.
"Rosemary." I answered. "Scratch it and smell it."
He was confused as to where to scratch it. So I came around the desk, scratched its general scratch spot, and handed it to him. He smelled it. He was impressed.
"Scratch and sniff." He said.
"Scratch and sniff." I responded.
He asked "What is the difference between an herb and a spice?"
"An herb is the leafy part of the plant. Spices come from the roots and seeds and other stuff." I replied, winging it.
"Oh." He said. "So the herbs are the leaves and spices are the rest of the plant?"
He started to walk away, and then I realized I'm at the library and have a higher responsibility to accuracy than just winging it. "That's just off the top of my head." I said. "Do you want me to look it up to be sure?"
"No thanks. I'm good."
As soon as the guy was gone I looked it up.
My answer was right.
