Interesting points one and all, just to confirm I raised the question as we had a meal spoilt by excessive smoke from several tables all around us. We were under cover in a balcony area. We didn't complain just smiled and got on with our meals, we were on holiday, it's what you do. It's not practical to move mid meal, but it may be practical to have non smoking areas? The alfresco aspect is relevant , outdoors not a problem, but in semi enclosed dining areas it can genuinely be unpleasant for non smokers.No prejudice,no nanny state storm troopers,no human rights articles being waved about,just a family tolerating the habits of others and asking a reasonable question of fellow holiday makers, Is it right to smoke next to fellow diners as they eat their meal?
