As I said, I cannot get any "Switchboard", "Reception", "Customer Services" or any form of human being to speak to (apart from Police, as described) at Edinburgh whereas I did once get a very good, sensible and helpful reply by phone elsewhere on a previous occasion, including name and title of the individual and encouragement to quote. Incidentally, tools such as scissors and knives are allowed but within certain limits. Thank you ladybirder, but no, the published general descriptions are all lacking detail to the extent I need to remove all doubt. Yes, it does appear the airports do not want to direct people to anyone who might help - it is not that people at the airports don't want to help, just that the systems don't provide a processing centre.
