Why is it..?

A man wakes up after sleeping
under an advertised blanket,
on an advertised mattress,
pulls off advertised pyjamas,
and bathes in an advertised shower.

He shaves with an advertised razor,
brushes his teeth with advertised toothpaste,
washes with advertised soap,
and puts on his advertised clothes.

He drinks a cup of advertised coffee,
drives to work in an advertised car,
and then... refuses to advertise,
believing it doesn't pay.

Later when business is poor,
he advertises it for sale.
