I'm going on a muskie charter in the morning. I don't target the fish but will be excited to try, especially with help from a pro if/when I land one. I'm not a big fan of toothy critters and haven't handled many fishing solo.
I will not care one way or the other if the guide fishes tomorrow. I am not attempting to learn techniques from him or lure presentation, or I'd be watching and listening closely. If it were a bass charter (as it was originally going to be), it would be way different, though I still wouldn't be offended if he were fishing or not.....though I would be grilling him/her much more for what he is looking for depth/structure wise, presentation, specific locations he's going to (and mentally noting them to return with my pontoon), etc. Tomorrow is all about doing something different and enjoying the morning, albeit with temps 25-30 degrees below average to start. I hope to get at least one for the sake of checking yet another species off my list.
I guess it really depends on the situation and the attitude and opinions of the paying customer, and if one is in doubt prior, ask questions before booking.
