Meetings can often appear to be noisy, boisterous affairs to those from cultures more accustomed to a reserved, calm approach where everybody politely awaits their turn to speak.
In Greece meetings are designed to allow a lively airing of views where strong personal opinions, passionately expressed are appreciated. Everybody is allowed to speak but you have to expect that you may be strongly and emotionally disagreed with. Such open, emotional debate is seen as both stimulating and essential if the correct decisions are to be arrived at.
Formal meetings with set agendas are arranged only for the most important of issues and 'normal' meetings are much more likely to be spontaneous and designed to keep everybody abreast of developments, plans, information etc. In these types of frequent, informal meetings agendas will rarely be produced and minutes are unlikely to be circulated after the meeting.
