Good evening everyone. 
Customer service...Let's don't ignore the fact that in Switzerland majority of people here hadly smile as in their nature. Sometimes the employer is constantly yelled at, not well paid in appreciation of their hard work and respected, taken adventage of due to their personal situation etc...
That affect the customer service also... it's hard to cope with all this and still give good customer service at thesame time.
Is rarely you see a smiling face with all that thoughts in their heads, except the person has a positive spirit and a smiling freak like me.
Lets put ourselves in their shoes for a moment... And try to smile at them to get a smile back. If we need their service. :)
