I have been working in customer service jobs for years and one of the required skills is ability to engage in small talk. A question I get asked, sometimes multiple times a day is, "How is your day going so far"? Usually when I have just started work, and have only been awake for a couple of hours by that point; or when I'm really busy, being run off my feet and am clearly stressed out. The only real option is to cheerfully answer "it's fine thank you". Nobody wants to hear that I'm stressed out or tired. It infuriates me when I get asked this question, I guess because it is so inane and thoughtless.
