I am very familiar with customers which fall into an example of a primary group. This particular group, customers, definitely contributes to a social capital to its members whereas it makes up what a company consists of. All companies have a huge main goal in common which is to satisfy their customers wants and needs. What company doesn't care about what their customers think of them? All companies consist of wanting to make their customers feel pleasant after doing business with them. Customer service is a huge important thing within companies, big or small, because customers are what affects their business. In my opinion, customers should be considered a secondary group because they are permanent. Not every group of customers are going to be the same exact people, but customers in general never go away forever. Different customers come and go but in general "customers" are all one big group of people. They are what make up a company, without them there is no business or money made up.  The relationships between companies and their customers is purely official and formal which falls into the secondary group characteristics. Customers are from all different backgrounds and cultures, they are not all the same,descent wise, which is what primary groups consist of. Lastly, secondary groups have a special purpose within a special assignment or duty in society, and this is exactly how people work with customers. All customers have their own individual different requests which companies work with. Not every customers request are going to be alike and every business related situation will be different from one another.  This is why customers should be considered apart of the secondary group rather than the primary group.
