This chapter presents the preliminary result of his ongoing fieldwork in four weekly open-air markets in the Lisbon Metropolitan area: Feira de Carcavelos, Feira das Merces and Feira de Monte Abraao, and Feira do Relogio. Cigano vendors create an acoustic place through their shouts. The aim is to appeal to people to discover directly what products are really worth, to involve themselves in terms of visual, auditory, olfactory, tactile, spatial, cognitive, and behavioural engagement with the goods and social engagement with the vendors in a relationship of exchange. It is exciting to think that cigano sellers can in some way be social and economic protagonists, or be part of the global consumer society of late capitalism. The author focuses on What happens is that shouts and calls work at the borders of the exchange relationships between cigano dealers and non-cigano customers.
