It's a basic design pattern that every software engineer should know. But without it, a glitch in communications could cause a transaction to occur twice, so cash registers appeared to be down. And worse, the logs were too poor to report the retry event. So many of the issues weren't caused by the complexity of the system, they were basic bad coding.
