There are all sorts of ways that employees can leave an impression on customers, not all of them intentional or good. A recent story in the International Business Times described an incident in which a British coffee shop customer observed a somewhat shocking message on another visitor's receipt left behind.
The message contained an expletive, was derogatory, and seemed to be directed toward all of the shop's customers. Whether it was programmed intentionally as a prank or left in accidentally seems to be unclear, but despite an apology from the owner, the offended patron in question said she felt "there was no hint of apology or embarrassment" among the staff. This is exactly the sort of perception that the right online customer services staff can make a well-informed attempt to prevent.
Even if your company's support team won't be handing out receipts to patrons, there's no guarantee that a mistake or rude message won't slip through and cause you some large-scale difficulty in terms of your image. And if this instance sounds a little too far-fetched, there's evidence of several similar occurrences taking place last year. One notorious event widely circulated on social media at the time included an employee responsible for a receipt that included a racist epithet, apparently targeted at a customer of Asian descent.
Consider the overall investment your company is making in its growth and greater reputation by choosing reliable answering services. You can not only expand the number of people who are interested in you but also mitigate troublesome situations like this if they chance to occur by accident.
