Most workplaces have tea/coffee making facilities. Why don't they take their own sandwiches? I did that for all the years I commuted to an office. It's no big deal. I know some folk can't cook but is there anyone incapable of making a sandwich?
In the same way that people can do their own cleaning, do their own decorating, do their own gardening, walk their own dog, mind their own children, make their own clothes, cook their own fish and chips, (probably) cut their own hair and tinker with their own car. .
On the other hand, if you are one of the millions or people whose job encompasses any of the above I expect you depend on the fact that many have neither the time, talent or inclination to do them.
I thought this thread was about the economy and anybody who cannot see the complex but apparently fragile interdependence of all its component parts has missed the point completely.
