I’d like to modify that beme and ask you this question. “What’s the smartest thing you ever did for your customers?” the original question wouldn’t allow you to mention marrying your wife or having kids. For this customer service question, let’s say you can’t use giving a price discount or a freebie. I’m actually looking for a process here that impacts either a segment or all of your customers. For example, empowering your employees to handle complaints without first seeking approval from higher ups. Or providing dedicated call center support for your best customers in such a way that they’ll get more experienced help faster.
If you can’t remember what the smartest thing is, or, if it was a long time ago, perhaps you should start thinking smarter.
