THE TYPE OF INDUSTRY THE BUSINESS OPERATES IN- Here are some examples of industries where most businesses remain small: hairdressing, car repairs, window cleaning, convenience stores, plumbers, catering. Businesses in these industries offer personal services or specialised products. If they were to grow too large, they would find it difficult to offer the close and personal service demanded by consumers. In these industries, it is often very easy for new businesses to be set up and this creates new competition. This helps to keep existing businesses relatively small.
