Don't make me laugh cretin. Algerian cuisine, while part of the larger Arab family, don't hold a candle to the diversity and influences (outwards and inwards) of Saudi Arabian cuisine. Numerous native Saudi Arabian dishes are famous across the Arab and Muslim world (in fact world) and have influenced more cuisine than most others.
I don't want to insult a brotherly country (Algeria) or people just because of a stateless Kabyle fanatic like you, but as far as hygiene goes, Algeria is lightyears away from KSA. Living standards included.
KSA is a stone throw away from the real Mediterranean (in fact a basin country), meaning the Eastern Mediterranean (the most ancient part of it and the culinary richest) so if that is an argument that is supposedly relevant it fails big time.
KSA (Arabia) was the center of the world's largest trade (Indian Ocean/Arabian Sea) trade which enriched Saudi Arabian/Arabian cuisine more than most other cuisines of the world and long before those spices, fruits, vegetables reach the periphery that Algeria was/is, aside from the Roman period and Arab conquest.

A trade that Arabs (Arabians) controlled for millennia.
Algeria? Nowhere to be seen.
Give it a rest troll. Your pathetic troll attempts are just that, pathetic.
Now lamb, goat, game, chicken and tender baby camel meat is not supposed to be the most delicious and expensive meat feasts out there. Especially grilled or slow cooked naturally.
Not a rich, cuisine.

In a parallel universe.
One of the most famous drinks and most consumed drinks were created by Arabians (it's called COFFEE). That is a bigger legacy than anything Algeria has to offer or most country cuisines for that matter.
Go take your medicine and give it a rest. You forgot it as usual.
More than half of the world eats with their hands. Also this is done mostly by tribal people or Bedouins. Most people use spoon and forks. It depends on the dish. Some dishes are easier eaten by your hands (and also taste better that way) while other with spoon and forks.
Bread is a stable dish in KSA as well (oldest bread in the world was found in neighboring Southern Jordan, 14.500 years old) and also eaten alongside many if not most dishes.
All 3 methods of eating are used and there is zero problem with this.
I proudly use all 3 methods depending on the dish I am eating, the setting etc.
Nor is hygiene a problem as people wash themselves thoroughly 5 times a day (cleanliness is very much prioritized in KSA, hence the many fragrances) and before every meal and only use their right hand only for eating.
If you have a gathering of 100's or 1000's of people you eat larger portions. It's normal and logical. Especially in a culture were sharing is something normal and eating together.
I don't know why people who have a much older and richer culture (Arabs) need to copy Europeans who did not know what hygiene was (large percentage of Europeans) millennia before Arabs knew it and applied it. And I am not even going to mention how much Arabs influenced Spanish, Portuguese, Italian, Greek etc. cuisine. This is described in detail just a search away on Google.
I guess that KSA does not have this complex as we were never a Western colony (unlike others) nor were we forced to learn the conquerors language and adopt some of their customs while removing our own under pressure to fit in! That is also why we wear our traditional clothing (s - as there are hundreds of traditions clothing) proudly.
