Funny story that col. Maybe you should give the security guard a load of flyers to hand out to passing folk.
In my previous life running a office furniture company, before the internet is what it is now, I used to spend between £2k - £3k a year advertising with Yellow pages. They faxed over the confirmation which detailed the advertisement and all was correct so I signed and faxed back.
A couple of months later a copy of the yellow pages landed on my desk and my adverts were nowhere to be seen. I contacted Yellow pages and was told that my 2 adverts were indeed in the new new book on pages 138 and 192.
They had only gone and put my adverts in 2 completely random sections, if I remember correctly the sections were agricultural equipment supplies and rental cars.
Needless to say i got a full refund and havnt advertised with them since.
