In the episode Titled forget me...not in season 6

of charmed. You will see Piper walking in the street

and stops to help a father with his diapers

and you see in the back ground behind Piper a American linen supply truck pass by.

If the show takes place in San Francisco then how

is this possible.

American linen is a business of the Midwest portion

of the country only.

How does this happen unless Piper actually orbed

to Chicago just for this one scene?
