Brookshire Grocery Company Brookshire's Won't back their money orders! Hawkins, Texas

Brookshire's will sell you money orders, however, they will not even cash a money order drawn from their own store selling them.  Won't back the product.  If they won't cash their own money orders, does that mean they are fraud and who will cash them if the own store you purchased it at will not cash it?  This is ridiculous! 

Don't ever trust a company who won't stand behind its products in anyway.  I can understand there is a lot of fraud going around but why not say "we will only cash money orders drawn off our own store?"  Whom else to trust?
