Lots of good advice in this thread. I used to get pretty stressed whenever there was a bug or problem, or sometimes even when a customer would ask for help and I couldn't answer right away for whatever reason. It would be a lot worse if the customer was angry or upset. I've learned over time though that, somewhat paradoxically, these are actually opportunities to create a stronger relationship with a customer than you'd have otherwise. No one likes bugs, but if you show empathy and make it clear that you are prioritizing the issue, 99% of people will be grateful, and will come away with a positive impression. Usually the people who are most upset initially are also the most grateful when the issue gets resolved. Strong emotions are a sign that your product is important to them. They're also going to be the most willing to help you debug, and will report problems that others might ignore. All that said, you will occasionally encounter people who are pathologically angry, rude, and impossible to satisfy. With these people, you just need to keep in mind that it's about them, not you or your product. Once I realize someone is in this bucket, I remain polite and will fix any issues they encounter as I would with any other customer, but I don't engage with them beyond this. The worst that can happen is you'll lose them as a customer, which won't be much of a loss. It's obviously tougher if they're a big or important customer, but it's still not worth stressing about people like this imo--they could very well still leave even if you indulge all their bs.
