The Albert Cuyp market here, famous for its offerings of cheap clothing and exotic foods, is one of the busiest in the Netherlands. But while it still attracts plenty of shoppers, customers are increasingly wary of spending their money there, said Nicolas Steur, a 50-year-old fishmonger. Revenue at his stall, where he sells fresh haddock, raw herring and other seafood, has fallen by 20% compared with four years ago. "We still have about the same amount of customers." Mr. Steur said. "But they spend less money. People are cutting down on their expenses." Show the effects in the Albert Cuyp market.
