There is too much average to poor service in shops, hotels, restaurants, post offices, health centres, libraries, etc and service industries should be more selective in recruitment and more meticulous in managing front line service employees. I have also referred to *"mint crunchers" and *"gum chewers", more and more common on checkouts and service counters, maybe because mastication is now an essential part of the job description. It looks horrible. It is horrible. A sour face, especially distorted by the action of chewing, has no place in customer service.
*Add "water-swiggers" to that bunch.
This very morning, it was the health centre receptionist. A smile-free zone. As frosty as the pavement outside. Sigh. Where do they get 'em from? duh.com?
