Culture No.1

Immigration and the changing culture of England

"When immigrants arrive in England should they adopt our ways, our culture? Be informed about English etiquette? Do queue, do smile, do take your hat off indoors, do hold the door open for others, do walk on the curb side of a lady, do cover your mouth when eating, do shake hands, don't eat with your mouth open, don't burp in public, don't greet a stranger with a kiss, don't put your elbows on the table, don't stare at people."
(Rosie Winfield)

Or is English etiquette out-dated, even ridiculous? Does it still exist? How is English etiquette changing, if at all? What contributes to this change? Should we be more accommodating to the change of english traditions and embracing influences from other cultures?
