It's been a while since I last "walked out", but the one time I most clearly remember is this:

Informed this guy I was not going to work any further with him, took another job on and simply ignored his emails/texts/whatever.

Blocked him from calling me (Android blacklist).

I just saw him one or two times, to collect the remaining payments.

I've been pretty formal when talking him, and whenever he asked "I'm doing things" was my reply.
