I hate overly nice customer service, it's very fake
Why do you hate nice customer service?
Because I hate being surprised how kind a person can be, makes me feel empathy and I don't want to feel it for a moment.
I get your point, but it's normal for these type of people to be nice, especially in the service industry. You should be happy they are nice and not mean!
Meh. I don't feel happy at all since they are too nice.
They are just doing their job and it's quite typical for them to be that nice. How about trying to desensitize yourself a little more, and try to call more customer service to get some practice on being used to all the kindness? It might actually come to brighten up your day.
