Some tourists are less than respectful of the city's cultural heritage, according to Nardella. In June 2017, he instituted a programme of spraying church steps with water to prevent tourists from using such areas as picnic spots. While he values the benefits of tourism, he claims that there has been "an increase among those who sit down on church steps, eat their food and leave rubbish strewn on them," he explained. To boost the sale of traditional foods, the mayor had introduced legislation (enacted in 2016) that requires restaurants to use typical Tuscan products and rejected McDonald's application to open a location in the Piazza del Duomo.
