If you do scrape together a few minutes to get part of the codebase into your head (despite the open-floor-plan chatter), you've got no way to trigger that bug you think you saw.
But persevere anyway and diagnose it. Oh it looks like it's happening in someone else's microservice. File a JIRA? Bring it up at the next meeting? Try a different fix anyway. Happy with the fix? Wait in pull-request limbo until it's sorted. Release it straight into prod? You could bring down prod... Maybe you didn't really see that bug after all. Coffee time!
