Oh dear, oh dear. What is the point of posting anything if people are going to reply without reading it? I thought I had made it clear that a) the young man was arrogant, therefore, wobblybits, not friendly, whereas the conductor was friendly; and b) that I didn't see the need for any form of address such as "sir or "madam".
petra, there is no need to be unpleasant about my user name, and you might like to know that I had a perfectly friendly chat with one of the arrogant one's colleagues, from whom I got the information I wanted as well as a friendly chat about other matters. I am not given to scowling at people.
I've been lurking a lot on GN recently and have noticed that many posters are being picked on for what they have not, in fact, said, and find it sad that things have degenerated since we all started so cheerfully at the beginning of GN.
