It has happened to me a lot that when I am searching for an item in aisle in a supermarket and somebody says "excuse me" and passes me. What is a natural response to excuse myself here? What should I say?
In the Uk the most common response is...." [Silence] ", occasionally, it accompanied with a scowl - meaning "How dare you ask ME to move out of your way... I'm far too important!" or "Oh, I'm Sorry". Brits do tend to apologise at every opportunity - even if it's not our fault!
I usually try to smile sweetly as I apologise :-)
