"I think it's fine if they want to protest but they shouldn't block the plans of the people who have flown over here to see an exhibition of Leonardo," said Ben Garrett of Dallas, Texass.

Gerhard Jehle of Germany, who had bought his ticket in advance, shared that view, and said he was "badly informed about the extent of the strike."

"I don't understand how this happens," Jehle said. "Public transport doesn't function. The unions have to be controlled with an iron hand."
