Culture and Polite Manners | Would it be not polite to snap fingers or clap hands to get someone's attention in English-speaking countries? "As you heard, we use Excuse me to get someone's attentuon. We use it in restaurants when we want the waiter, for example. We never snap our fingers or clap our hands. Listen to David and Harriet in the White Horse Cafe." David: Excuse me. Waiter: Yes, sir? *This text above is quoted by intonation practice book. So I wonder does behaviours like snapping fingers consider impolite or people don't do it just coz of culture or customs? Or it differs from situations? Because in China, sometimes among friends, behaviours like clap hands to get others' attention is acceptable in my way of thinking. I hope my question is understandable. Thanks very much for reading!
