When one is single and travels about, eating alone is often (always?) the best option. Or, as one young thing said “Done leave, I want to be alone”. In Germany, if the restaurant is somewhat crowded you may find it is impossible to dine alone for long because they are usually not bashful about asking “is here free”, in which case you are stuck and then, make the most of it. They usually do not bother although I have had some rather interesting conservations. And some places will not seat you if they believe they can make more profit from holding out for at least a couple. Set where you have a view of the dining room , and then just observe, especially if families are there. Watching the group dynamics can be the best entertainment anywhere. I do think that it may be against the law in Naples, or at least deviate behavor.
