Interesting facts from customers

I am often on the receiving end of interesting snippets of information from customers, who are as you would imagine, a varied group of people with lots of different backgrounds. Tonight I discovered that the main ingredient for deer repellent is actually tiger pee.
How on earth an english born deer knows that a tiger is a lethal predator to be avoided at all costs beats me. But there you go. Maybe they are all born at Longleat and send round the country from there.
