What is the ruling on opening a cafe to serve tea and coffee without prohibitions, knowing that customers may sit for extended periods in front of the television or gazing at the street and passersby?

"Opening a café that serves tea and coffee is permissible, and its owner bears no sin due to some customers' prolonged stay or idleness. However, the café owner sins if he provides a means for haram, such as a television, unless he controls it by turning it off when forbidden content is displayed and allows only what is permissible."
