We really need to change that phrase. It has been a while since even the most foul gas station coffee could be bought with a pocket full of nickels. But lets go with the traditional phrasing, for now.

As mentioned previously, I have an online gig economy job where I make seventeen cents a minute. (Which, semi-related, means I need to work 3 minutes to get that proverbial cheap styrofoam cup gas station coffee.) I have short conversation with English language learners. How many hours a day I work at this job varies, but I think there were days where my entire work schedule might have been a single, 15 minute conversation. For $2.55. There is not a lot of language learning you can do in 15 minutes, but for some students, it is a small part of their daily routine to keep English in mind.

And for me, when I had a single 15 minute appointment of work, it was a workday. A fifteen minute workday is still a workday, for better and worse. For better because it gives some type of

combat power

The total means of destructive and/or disruptive force that a military unit/formation can apply against the opponent at a given time. (JP 3-0)

Trigger warning. Bad language ahead.

ChatGPT did it again. Give me a 'Prove that you're human' test, then log me in. Except you won't log me in, you'll fail, present me with an identical test, and fail again. At what point can I prove that I'm human by punching my screen in and giving up with (very human) impatience? Because right just now I am done. That should be a part of the bastard test. Increment a counter with every attempt, and offer me a "Fuck you shithead, I'm done!" button
