<human>: I've just becomes a freelancer and I was contacted to go work in an design agency for 3 days. It was my first day when I got there they were very impressed by the turn around and the quality of work, they'd asked me to maybe stay an extra day for more work.

So going with trying to impress them especially since they're my first client I finished the workload and the extra work in 3 days. Automatically assuming they would still want me in the next day, I got called to the side and told 'We're very happy with the work you've done and we will definitely call you back for more work, speak to you soon bye.'

Which at the time I felt an arse because If i had just done the work at the pace they wanted and not tried to impress them I would have got another days pay out of it.

Give me the gist of the text in a nutshell
<bot>: Contracted to work 4 days, finished work in 3 days. Got paid for 3 days when I could have easily stretched the work and got 4 days pay.
