Coffee as identity

Coffee as identity is not limited to Vancouver/Seattle culture.
Check out this quote from an office worker in Japan.

"Simply putting a Starbucks cup on my desk kinda makes what may have
been jumbled seem a lot cleaner. I can't give up that feeling," she
says. "Your computer, your documents, whatever is on your desk is
almost all company property, but your coffee cup is a symbol of your
own identity. Some people at work tease me about the cup being so big,
but the cup is also a way of expressing 'me' at work."
