What does Passepartout sell in chapter 23 of Around the World in Eighty Days, and why?

By that part of the novel, Passepartout has been separated from Phileas Fogg.  That is a big problem in general, but the immediate problem is that Passepartout does not carry money around like Fogg does. Passepartout is hungry and needs to find transport.  He needs money for both things, so he decides that he can earn some money as a street performer.  Unfortunately, the clothes that he is wearing do not look like something a street performer would be wearing.  They are too nice.  

Passepartout decides to sell his extremely European clothing to a clothing dealer.  He is able to secure some money and clothing that is more suitable for a street performer.  With the money, he is able to buy himself some breakfast from a teahouse.  

What is Passepartout's main role in "Around the World in Eighty Days"?

Passepartout acts as a dramatic foil for Phileas Fogg.  A dramatic foil is a character who is in direct contrast with the main character so as to magnify certain traits in the main character.  For example, Passepartout's past was one of flitting from place to place, which in direct contrast to the past behaviors of Phileas Fogg.  Ironically, just as Passepartout finds himself employed by one who is predictable and follows a strict schedule, Phileas Fogg does the unthinkable.  He accepts a bet to go around the world in eighty days.  While Fogg may seem cool and collected on the surface, Passepartout (and all his worrying) may be a reflection of the turmoil that is going on inside Fogg when things go wrong on the journey.
