Why do the authors of this chapter decide to talk to a patron of a coffee shop?

The coffee shop patron they are seeking is someone that they met previously, who expressed an interest in anthropology.

International students visit the coffee shop near their college, so they thought it might be a good place to find potential informants.

The authors are interested to know how non$-$anthropologists define culture.

The authors are sleepy and need a shot of espresso to continue working on their chapter.
