I don't demand anything of anyone. I just expect someone to react. Even just a simple grunt. I don't expect much. Simple "ok" would be enough. I would literary punch anyone in the face if he tried to serve me. I don't tolerate people lowering themselves as well as i hate when they try to treat me "well". Also: so what if it's free? I were making subtitles to videos for 2 years also for free. 20x to 40x 30min or longer videos per day, and i never complained. You know why? Because I decided to do it, so i have no right to complain. To be honest, i'm incapable of taking offense to anything, i just can't. It's physically impossible to me. So your offense seems childish to me.
"not in the best mood right now" nice... i've been depressed for last 15 years on top of many mental problems and anger issues. So please tell me how it is to have a bad day only once in a while, and not all the time. People have it worse than you, they even have it worse than me. So get over it.
