Apply Hanlon's Razor

Help me apply Hanlon's Razor ('Never attribute to malice that which is adequately explained by stupidity/ignorance/error') to this situation: '[Describe a situation where someone's action caused a negative outcome, e.g., 'My coworker submitted a report with significant errors.', 'A friend canceled plans at the last minute.', 'A company provided poor customer service.']'. Brainstorm plausible alternative explanations for their actions that *don't* assume malicious intent.
