How Small Service Failures Can Cost Companies Customer Loyalty

In a recent LinkedIn post, Stacy Sherman, MBA. CSP® discusses how a single poor customer interaction can undermine loyalty and urges companies to identify and repair the service moments that frustrate buyers. This article reports on Sherman’s post and examines the customer experience advice she shared.

“My new research found that 60% of customers leave after one negative interaction.”

Small moments can shape how customers feel

Sherman argues that companies may overlook routine service problems because they seem insignificant internally. For customers, however, those encounters can signal that their time and needs are not valued. She points to examples including chatbots that fail to connect people with a human representative, long waits to reach customer care, and a survey sent before a customer has received service.

According to Sherman, the significance lies in the impression these moments create across the buyer journey. A process that appears efficient from the company’s perspective may leave a customer feeling ignored or frustrated. Her post asks leaders to consider whether they know how customers feel at each point of interaction; she says audiences at her keynote speeches often tell her they do not know for sure.

Make the customer journey visible

To help leaders find trouble spots, Sherman recommends experiencing the company as a customer would. Her suggested review includes calling, chatting and making a purchase, then examining recent customer reviews and survey comments for recurring words such as “waited,” “transferred” and “frustrated.”

“Call, chat and buy from your own company the way a customer would.”

This approach connects operational checks with customers’ own descriptions of their experiences. Sherman’s advice is to look for patterns in both direct interactions and written feedback, rather than relying on assumptions about which parts of service are working well.

Fix one problem and track the response

After identifying pain points, Sherman recommends prioritizing the one that upsets customers most. She advises assigning a leader to own the fix and setting a deadline, giving the work a clear point of accountability.

Her final step is monthly measurement. Sherman suggests comparing how customers describe the problem before and after the change, and notes that AI can make sentiment analysis easier. The post does not provide additional details about the research methodology behind the 60% finding, but its practical framework centers on observing service firsthand, acting on customer feedback and checking whether the experience improves.

“create a positive emotional connection at EVERY interaction.”

Sherman’s broader argument is that repeat purchases and recommendations depend on the feelings customers carry away from everyday interactions. Her post frames customer experience improvement as an ongoing management task: identify a painful moment, assign responsibility for fixing it, and measure what customers say afterward.
