It is also inhuman to expect everybody to be smiling all the time. People have to realize this. I work in retail and nothing infuriates me more than hearing a customer whine about a service person who didn't smile for them. Meanwhile, that service person may have just heard of a loss in the family, a partner had hurt them, a child or loved one might be in hospital or sick, a threat might have come to evict them or any threat in life. Be realistic people!!. Crap happens to everybody and if a worker doesn't smile at you and make you feel warm and fuzzy every single time you go through a line-up, try to consider what kind of day THAT person might be having. I agree, Lizard Lady. We need to allow people to feel what they feel and not try to be "cheerleaders" 24/7. It is humanly impossible to be such a person.
