Back in the stone age, I worked at 7-Eleven while in university. Nothing was really computerized at the store level then, even cameras were rare.
What was done all the time was a simple, templated, paper-based process that managers went through each month. I believe the gist of it was that it recorded sales for each shift in the month (7am-3pm, 3-11, 11-7), and who worked them. Some simple stats highlighted low sales correlated with employees, to point out who was likely entering smaller prices in the till and pocketing the difference. Now it's all bar-code scans of course, but it was a common problem at the time.

Great point! I know some pretty advanced statistical analysis is used in my friend's case to detect anomalies in ordering, shipping, etc.
