Pitfalls of Freelancing

As freelancers and job providers what are your biggest issues with the freelance market?

I'll start it up:
Communication: When ever I'm designing for someone I have to send over my file links via email or messengers and then wait for what seems like an eternity to get feed back on it or desired changes.

Fear of getting ripped off: I hate it when I deal with someone online who seems honest, then they end up being shady or shiesters when the bill comes. The predetermined price is now "out of their range" or they offer some sort of profit sharing scheme, and the logo ends up on their site anyways.

Your turn to vent!
