Working, regardless of industry, can be hard if you're like me. They expect both speed AND accuracy. I can only do one or the other, and it's all or nothing. If I'm accurate and do my job well, I'll be too slow. If I'm quick and can finish in a timely manner, it's all wrong and I might have to start over. But they want BOTH.
The fact that I am expected to remain calm and polite after a customer just called me stupid just because they didn’t like the answer I gave to their question, is infuriating.
