In Paris, my sister picked up a rubber (7)
I believe the answer is:
masseur
'rubber' is the definition.
(someone who rubs or massages people)
I don't understand the rest of the clue.
(Other definitions for masseur that I've seen before include "rubber found" , "Parlour worker" , "Professional rubber?" , "One who kneads and strokes" , "One easing tension" .)
