When in Rome, take a hint and put away your selfie-stick, says Venetia Sherson.
At Diocletian's Wine House in Split, one of Croatia's most venerated eateries, the Italian visitor at the next table beckons the young waiter and asks conspiratorially - but loud enough for all to hear - for the ingredients of the sauce he has just eaten.
It seems a genuine inquiry. But when the waitperson replies, Giovanni announces, "Not enough tomato. Please tell the chef." When the main course is served, he repeats the performance, smirking at the sycophants seated at his table. "At what temperature was the lamb cooked?" The waiter's back stiffens slightly. "I believe around 180C." Giovanni flashes his teeth. "Tell him it should have been 160." He wipes a morsel of meat from his mouth, looks around for approbation; finds none and leaves no tip.
There is a common predisposition among older people - of which I am one - to believe the world is getting worse. I don't subscribe to that. But, as a traveller, my impression is that rudeness and discourtesy is on the increase among tourists. As far as I know, there is not a standard way to measure bad manners. But these are my bugbears.
SELFIES IN SACRED PLACES
Yes, I know it is tempting to have yourself in the frame with breath-taking spiritual places and great works of art. Resist the urge. Your face in the foreground will not enhance the splendour of the background. Especially, put away your selfie sticks. These wands of narcissism are dangerous to other visitors and an affront to those of us who like to stand and gaze without them. Fortunately the list of museums, galleries and monuments banning them is growing. Sticks are now not welcome at the Palace of Versailles in Paris, the National Gallery in London or even the Colosseum in Rome.
