It's amazing the difference in countries. In the USA the customer is God and client servicing is a thing. Here in Germany we are just waiting to get mauled at the post office, at the grocery store, at the Drs office because people do not need to be respectful to customers and are used to being rude, mostly because they hate their job but are forced to do it in order to get social security after x no of work years. And no, voicing out your opinion does not help in a place where disrespect is a way if life.
