Have you noticed? (Part 4)

Have you noticed that you always find shoe repairs and key cutting in the same shop? It's not as if the two areas are intimately related. Maybe the reasoning was, "People who wear shoes also tend to live in houses, so this is a sure-fire business idea". I wonder what other combo businesses we could create? I've noticed that people who own pets tend to wear clothes, so I think 'Smartpet: Dry cleaners and pet food supplier' is a winner. Or what about, 'Betspecs' - bookies and optician - for people who like to gamble and also own a pair of eyes.
