I've been doing customer service jobs of one sort or another since I was 16, starting with working at a fast food. I also have done a myriad of years and years of call center work. I'm talking to people on phones. And then I've also been a bus driver and a taxi driver, which I also consider to be customer service due to the fact that you do need to deal with customers in a face-to-face environment, which is very important.
