In reply to Gary Latter:
> Does that sound fair,
It sounds like the quickest and most convenient way of dealing with a request. Look at it frm the point of view of the MCoS person who received the letter. There's a reasonable chance they're quite busy. Do you:
a) give the letter to someone standing next to you and getting the request dealt with in seconds flat, or
b) go to your list of guides and phone someone up, only to find that they're out, so you leave a message on their answering machine. They phone back the next day to say they're busy on the requested day, so you have to try to someone else. You leave another message and then you remember they've gone to the Alps for a week and won't get back to you for some time.....
