@GG54 - I agree with you and I could probably have phrased my comment better - certainly didn't mean to imply there was anything wrong with delivery drivers/foreign delivery drivers/anyone else. Some of the delivery drivers are lovely and very helpful. And our postman is yummy in so many ways.
but
last week we had a delivery of gas bottles intended for a house about three roads away. Driver was unable to understand that we were a different road, although they both began with P. All he kept doing was pointing at the pad he wanted me to sign, and the name and address. I kept shaking my head, eventually I wrote down the name of our road and by lots of sign language directed him to the right road and drew him a map. If he hadn't been getting a bit frustrated and angry towards the end it would have been funny. Yes he could talk, he wasn't deaf, dumb or stupid - what he did say was all in very heavily accented English and generally monosyllabic.
happens quite often to us.
