making maps

I just typed 'uk map' into google as last week I was trying to explain where places were for the kids when we were reading a book. I resolved to take a map of the UK and a map of the world with me this week. So I found a clear enough map and printed it off. When I went to pick it up from the printer there were random comments made on certain places in the UK which could only have been made by someone in Durham. 1.- What are the chances of the 859,000 maps available, that I chose this one to print off. 2.- How completely and utterly random!
