One more entry into our arsenal of
toilet advertising tactics - the talking
roll holder (around $30 in British money). "The Talking TP works very simply. Hit the record button, leave a suitable message such as “we’re trying to conserve paper, please use both sides!” and then place inside a toilet roll. When the paper is pulled, your message bleats out via a concealed in-built speaker."
