Speaking as someone who’s been in customer service for 34years and counting: when everything goes well, the symbiosis between a service team and their customer — whether a singular exchange or a recurring relationship — makes for a heartening occasion that both sides can appreciate. They pull off the quid pro quo between creator/provider and receiver/consumer, and everybody wins.
When things go wrong between the two parties, the results can be anywhere from mild disappointment to small-scale war. The customer gets full of themselves, or the employees show up in a foul mood, or there’s a miscommunication between the sides that could be resolved with some calm negotiation, yet isn’t. No one wins, everyone’s miserable, and it’s another round of cringing when they look back on That One Time years later.
