I worked at the  Government Services Ministry around 1990, and only 25 to 33% of purchases had bills of lading or purchase orders attached.I was a accounts payable/receivable clerk for about 1 1/2 years through an agency. Purchasing clerks phoned their relatives, friends and lovers to obtain more expensive product more quickly. One man who used to work in purchasing and now worked in marketing tried to get me to signoff on a purchase of $250,000 which I and my controller refused to do.I government is more expensive
