What does Cornerstone do you ask??? It is a family-run local busines that does work all over the nation. They sell prison equipment (uniforms, guard towers, stainless steel toilets and sinks, beds, security glass, you name it they sell it). There is also a construction side that does a lot of work with architects who design prisons and other detention facilities.
So now, when people ask me what Brent does, instead of explaining that he works for a wholesale plumbing supplier that also sells lighting and appliances (a toilet salesman) I will now have to explain that he works for a detention equipment supplier (a prison salesman).
