I work as the entire I.T. department of a small business which products are web based, so naturally, I do tech support in said website directly to our clients.

It is normal that the first time a new client access our site they run into questions, but usually they never call again since it is an easy website.

There was an unlucky client which ran into unknown problems and blamed the server.
I couldn't determine the exact cause, but my assumption was a network error for a few seconds which made the site unavailable and the user tried to navigate the site through the navbar and exited the process he was doing. It goes without saying but he was very angry.

I assured him there was nothing wrong with the site, and told him that it would not be charged for this reason. Finally i told him that if he had the same problem, to let me know instead of trying to fix it himself.

The next time he used the site I received a WhatsApp message saying:
- there is something clearly wrong with the site... It has been doing this for so long!
And attached was a 10 second video which showed that he filled a form and never pressed send (my forms have small animations and text which indicates when the form is being send and error messages when an error occurs, usually not visible because the data they send is small and the whole process is quite fast)

To which I answer
- It seems that the form has not been send that's why it looks that way
- So... What an I supposed to do?
- click send
It took a while but the client replied
- ok

To this day I wonder how much time did the client stared at the form cursing the server.
