Listeners to BBC World Service told us they hate it when fellow diners chew noisily or talk with their mouth full. But what is polite at mealtimes can vary wildly according to where in the world you are and who you are with.
Ruth Alexander visits London's City of Westminster College to meet some of its teenage students, to find out about their different backgrounds and what good manners mean to them. She visits an exclusive private members club in the heart of London's West end to talk to Rupert Wesson, a director and coach at the British etiquette institution Debrett’s. And she hears from Japanese language tutor Chika Nakagawa about the rules that govern mealtimes in Japan.
Plus what if you are thrown into a world you weren't prepared for? After tough beginnings and through sheer determination Reggie Nelson built a career in finance. He tells Ruth about his extraordinary path to success and how he got through his first formal business dinner.
And what about when a restaurant meal brings out the worst in a customer? Mo Abedin, owner of Sticky Rice Thai restaurants in Dubai and Abu Dhabi talks about how he and his staff deal with the nightmare diners who have forgotten their manners.
