I got my first appointment with my first freelance client today as I'm trying to earn some money on the side. She contacted me after the guy before me hasn't delivered in more than 2 months.

Her: So how much do you think its gonna cost me.

Me: Well the minimum rate for a site like this is like €1000. But since you are my first client, I'm willing to do it for €700.

Her: The guy before you only charged €250...

Me: I'm sorry I can't do that. I might get to 500 if I cut some corners, but I can't make any promises.
Inner me: Look where you're 250 has got you... You haven't seen anything in return...

Her: Proceeds to whine about how it's still waaay to much ... And how she will get me more clients etc. (Yeah right...)

I'm fiddeling around with progressive web apps. I made something and hosted it on a subdomain. Today I made a typo and found my app on an other domain. All my assets and files are copied there. He even uses my SSL certificate.

It's not that spectacular. The app is nothing "revolutionary". It's just the first time it happend to me.

Have you ever found your code on other websites ? How did you react ?

Put everything on paper, especially if money is involved.

Did a few freelance gigs that ended in big disputes. For example, people that think you make a website from scratch in less than 2-3 hours and accuse me of charging too many hours.

Best one was a "friend" who asked me to build a site, after more than 6 months of making "changes" that were actually updates without seeing a dime. I gave him his last chance and terminated the host. Still holding the domain name :)
