I'm always nice to the call center people, they've been good to me. Sometimes the automated system is so frustrating that I worry my frustrated tone of voice carries over to the beginning of the call with the actual person so I feel like I have to be like "holy hell the phone bot is annoying, if I sound frustrated I'm just recovering, it's not you." I totally get that it's a hard job, though. I always feel bad when the person is super apologetic for taking some time and I'm like "no, no, it's cool. Take all the time in the world, if you can fix my issue I'll be so happy." Just makes me think they get pressured a lot by bosses / customers :|.
