I have a different view, those rudeness were measured in terms of saying words like thank you and pleases. Rudeness were measured in terms of holding the door and keeping a smiley face. Rudeness were measured in terms of hugs and kisses. Which is not aplicable to neplease culturally. We have our own way of being polite. We always ask for a tea when someone comes to ur house. We welcome strangers. We may lack some body language gestures but we are kind and humble. In other words we are polite in our own unique way.
