I was told by a friend that if someone offers you help and you reply "No, thank you there,s no need to." it sounds rude. Is it really so?
A-"Would you like me to help you?"
B-"No, thank you, there's no need to, I guess I can do it myself."
That doesn't sound rude to me at all. You can just say "No, thank you" if you like. Really, the important part of it all is the "thank you", showing that you appreciate the offer even if you are turning it down.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
