LOL!!! Perhaps your processor thinks you're a "special needs" hunter that needs all the help you can get. He doesn't tie your shoes for you too (without additional charge), does he??
Once again, your words speak volumes of what kind of person you are.
I just think it takes away from the dead weight you have to fool with and to me it does add to the experience as much as anything that is neccesary to be an effective hunter.
Not to mention that I personally would consider it RUDE behavior to drop off a deer to a processor or anyone, that has not been gutted.
Many times growing up, my friends and I would kill squirrels and rabbits while out hunting and then decide for one reason or another that nobody really wanted them. So we would take them to somebody's house (usually someone of very modest income) that we knew would appreciate them.
However, even though this meat could be considered a gift (for which, technically they should have been grateful for, no matter what), we would have never have been so rude to drop off the animals unless they had been properly cleaned. Just the way I was reared.
It has something to do with respecting the animal as well, as others have mentioned.
Scoop and lift, innards don't weigh a ton. Why is it disrespectful to the animal to not field dress it? And if the processor says "You're bringing me business, I don't complain about it" there's no rudeness involved. As far as giving meat away to another, we do that with fish all of the time. And no, we don't clean them. Those I know are happy just to get what you give them, those who complain about them not being cleaned are those who are considered rude. Ever heard the expression "Never look a gift horse in the mouth?"
I'm sorry if I hurt your feelings, still, it is the way I feel and I'm just being honest. One thing I guarantee is that many on here if they are experienced hunters,whether they will express their opinion so directly or not, would, if they saw an anonymoushunter driving down the road with a dead and UNGUTTED deer in the back of his truck, generally remark "look at that idiot who hasn't even gutted his deer" to their companions.

Of course it is different if your processor has alterior motives for WANTING the guts or, like I said their are other special and unusual circumstances.
I was being honestalso.And I guarantee you that if you made a remark like you did to anyone in my neck of the woods, worrying about whether or not they field dress their deer would be the least of your problems. They'd have 15 or so Z-71s and a heap of rednecks around you in a heartbeat.
Just worry about yourself, not about what others do and how they do it. I have my opinions on shooting deer with a high power scope and rifle, but I choose not to call those who do names. Isn't there something more productive about hunting you can focus your efforts toward like helping others?
