I just realized why you should never help people with tech problems, at least for free.

I went to grab the rent from a family that lives in my grandma's childhood home.

The father asks me if I could have a look at their new internet connection because it doesn't open any pages on the browser.

After fiddling for about an hour and a half trying every trick in the book and gently explaining to his children how everything is supposed to work (kids need to learn how these machines work imho) I ask him to give me his service provider number and confirmed that indeed the problem was that the connection wasn't activated on their side. Installed chrome, set the date,/time because it wouldn't sync and told them twice how to get past the certificate problem should some page not open. Smiles all around, all is well.

Fast forward next to next morning and I get a call from the guy telling me his internet doesn't work because he pulled out the power cable for whatever reason. I instruct him to restart the router just to be sure and then ask him what's on the screen. Turns out it was the certificate problem. I try as best I can explaining and reminding him how to get past but he doesn't understand. He goes on asking me to "come over for 5minutes and have a look at it". I politely tell him that just the trip is half an hour and that I am currently in the middle of exams to finish university. His tone becomes increasingly passive aggressive as I tell him again that it's isn't possible for me to make the time for a one hour round trip at the moment. Hangs up with a grim "right right whatever you say."

First time I was genuinely angry at a person being both so ungrateful after helping them and not even trying to fix something after I took the time to explain it to them.
