Note: CUSTOMER_1-4 edited to protect the innocent

Ray mentions that this is in fact the best named function in the entire system. The rest are called totally random words such as "yellow", "f", "harry", "doit", and rather ironically, "foo". But my question is ... does the system contain a DoNothing() function?
