Already existing website, I was asked to do a few things to redo. Code is a mess, 0 comments, oldschool technology. Completely static html site of a small company, nothing extreme.

Client: okay, could you please add 2 more items to the navbar for the 2 new pages?
Me: yes, here they are. Since it was already full, font size had to shrink.
Client: it's okay

>> Fast forward 2 weeks, full of similarly easy modifications.

Client: could you make the font size of the navbar larger?
Me: not really, we will lose responsivity
Client: do it anyway!

>> Fast forward to next day
Client calls me that it is urgent to 'do something immediately' with the navbar because it is broken and I am a 'horrible webdesigner' for making a mess of her website. I was told that it is not her job to make it good look and that I should 'use my eyes better'.

After 2 minutes of a lecture on webdesign she let me tell her how a responsive website should look like and to achieve that we should better restart the whole website. At that point I was the idiot who just wants to get more money and that I won't be able to do that since I am already unable to finish these few tiny things she asked for.
