A typical street cleaners' kit, shown here, is a good example. Brushes are invariably made of twigs; cleaners carts of old prams or trolleys with plastic buckets or boxes tied on with string. Why buy a plastic broom, or a pre-designed dustbin cart? Well why indeed, except of course in London that is what the street cleaners have (whether contracted publicly or privately).
Another example is luncheon vouchers (I have also had post-it notes as cloakroom tickets). We used to get these at work; and each month someone would make photocopies and cut them out individually with scissors. But I can't really explain why I find this odd.
