Bill, a supervisor at a grocery store, continually monitors employees' performance and often goes into the stock room to make sure they are working. He reprimands employees who talk to one another while working the registers, even if no customers are present, and surveys the breakroom to ensure employees do not take longer breaks than allotted. Bill most likely uses $q,$ assumptions when dealing with employees.
