In some cases there definitely are certain fees involved, but this is just not realistic. So from there I assume you are talking about something different, but just don't know what describe your issue properly.
I am using Coinbase quite regularly to pay out certain people, and thus far everything has gone through smoothly without any issues. The only issue I ever had was a 1 hour delay to withdraw Bitcoin.
Actually that happened to me as well. Most of the time the transaction were empty or just with a couple dollars in it (10% could be realistic).
You understand that sending just 1 or 2 dollars to an exchange means you can't use them...and you even paying fees!
