No problem
Easy and friendly. It tells them the favour cost you nothing.
Examples
"Thanks for the lift." "No problem, any excuse for a drive."
No problem at all. Let me know if you need anything else.
In a conversation
A: Thanks for holding the door.
B: No problem.
Common mistake
Not: Never mind.
Say: No problem.
Vietnamese speakers often translate their usual reply into "Never mind". But in English that means "forget it, it doesn't matter".
