AFTER a promising May and June, Steffen Knoop has seen his sales dip by 30%. His small Hamburg-based company, Wascut, sells cooling and cleaning oils for big machines, including those that make cars. “I have a pretty good window on the economy,” he says. Mr Knoop wonders whether the dip is caused by people taking extra long summer holidays or something more serious. Others with a broader and more long-term view of the economic landscape are asking the same question.
