Final answer:
The commonly referenced statistic suggests about 50% of retail customers might not return to a store due to poor customer service, although this can vary based on several factors. The precise figure would need to be supported by specific and current survey data.
Step-by-step explanation:
When considering the percentage of retail customers who would not return to a store if the customer service is bad, different studies and surveys can offer varying results. However, as per your question, you are likely referring to a survey or statistical study that has identified a specific percentage.
Although I do not have access to specific customer service statistics post the knowledge cutoff date, traditionally, it's widely acknowledged that customer service is critical to retail success and a substantial number of customers may not return after a bad service experience.
Taking into account the options provided, 50% is a plausible answer since it's often cited in various customer service reports and industry surveys that a significant portion of customers will choose not to return after a poor experience. Nevertheless, the exact figure can vary depending on the industry, the geographical location, or how 'bad' the service was considered to be.
Therefore, the correct option is Option 3: 50%.
