I have never seen that here. In the university usually the teachers even treat the students by "você", I had older teachers who treated the students as "senhor" and demanded to be treated as "senhor professor".
We only share plates in the street in a bar, not at home. At least in my family.
The traditional lunch is a first plate(vegetables), , a second plate (meat or fish, which is the main dish) and dessert, and after that, it was "café, copa y puro"(coffee, liquor and tobacco), and during all the lunch, usually wine.
in any case, compare a region with a lot of regions doesn't make much sense
The loved chupito(s) after the lunch, a classic :icon_drunk:

Where I live, it is difficult to see someone smoking in public a cigar,excepting in open air public celebrations, those who do it ,prefer to do it at home.
And those who smoke cigars are mostly older people, although there are also younger people or middle-aged "connaisseurs" who do it, but it is no longer "popular".
Spain has changed a lot the last 30 years. Too much. e have, or have been forced to move away from many things that we were.
We have left behind many bad things, no doubt, but also many others that were good, and that were part of how we were.
I suppose it is a generalized fact of all peoples, but in our case, I believed that it has been a more sudden change and in a short time.
