Company had issues with people not submitting trip reports to explain/justify/summarize expenses. So they linked the systems so you couldn't get reimbursed for expenses until you submitted a trip report.

Fine.

Salesman was on vacation with his family and happened to be in the same town with one of their customers. Decided to stop in, say hi, and check on them. When he got back, he was the good little employee and wrote up a trip report. After submitting it, the system kicked him into the expense report system, where he put in $0.

Two weeks later, he got a check for $0.

Two months after that, he got an automated nastygram from the controller's office asking why the check hadn't cleared yet.
