This issue is more of a USCG than WDFW issue, according to USCG someone buying you breakfast, gas, etc in trade or as a good gesture for taking you fishing constitutes a boat for hire which means that you have to have your CG License when fishing in Federal navigatable waters. I think if WDFW wanted to push the issue they could also site you for guiding without a license in trade for breakfast, gas etc.
