I'm thinking of working in customer service and sometimes I have no clue what I'm explaining to our clients
How do you feel about your clients?
I hope they die and no one will be able to contact them then.
I hope you're joking, You shouldn't deceive other people about your skills. If you hate working with clients, it might be better to get a job with less customer reaction.
I just want my clients to die and go away, I want to work with robots.
It sounds very upsetting that you want people to die. I don't think customer service is the best choice for you then, so how about quitting and finding that robot job you want?
