I interpret this as B's question to himself, not to A, meaning "maybe I should consider going shopping?"  And it's probably not even a real question, although the vocal pattern is the same as for a question; when written, a question mark at the end is the only way to indicate that intonation.

Does the question mark mean this is a question?
I use drupal 6 and ubercart2. Loading of cart and checkout page takes a while so I am thinking about removing any js and css files which are not used on specific pages.
What would be the ideal way to do it? I know about js agregation but want to try the first approach.
Thank you very much.
