No leftovers please--venting

Toss it and have no guilt.

Why wouldn't you just eat the stuff?  And why on god's green earth would leftover cookies be a problem?  They're cookies!!  And water???  How can bottled water (I assume its bottled water) be classified as leftovers?

First World Problem

this OP is actually the very definition of a FWP.

Oh my! I'm kind of mean, but I'm not THAT mean over a vent! LOL

Darn those guests bringing food to help contribute. I can't believe the nerve of them

I'll validate you! I hate to waste food so I would have been irritated because what you listed probably would have gone bad before we could get to it especially since you already made plans for meals.  

I was kind of thinking the same thing...damn those helpers!! 

I first read it as they brought the stuff to your house, but after reading your second post, it sounds like you are all away from home, is that correct?

We totally do that to my SIL. we buy stuff to eat at the condo and then she ends up taking the leftovers home since she drives and we fly. I never thought it was a burden for her.

If you don't want it, throw it away in front of them.

But also see their point in bringing the food. Maybe a recipe or meal plan called for green onions, I can't just buy one, so they buy the bundle and there are leftovers.

I want strawberries and one carton isn't quite enough, but two gives leftovers.

Maybe have one day at the end when no prep cam occur until all the leftovers are eaten or used or thrown away

We always plan the last day or two to have leftovers for each meal when we are at the cabin for a week. We still end up with leftovers but not quiet as many. But I get it.

Okay that really made me laugh!

Cut Watermelon and cantaloupe, pea pods, and asparagus would need a cooler to transport. Maybe the OP doesn't have the room to transport it home, so yes, it becomes an inconvenience especially if the OP asked them not to leave it.

DH and I are cabin people too, so I completely get it. Been there, done that more times than I could count. People mean well but they don't have a clue.

The problem with what I've bolded is that in the case of fresh produce is that it typically requires refrigeration especially in a hot car and if you're traveling any distance to get back home that means having space in the cooler for it. Also depending on what it is, it could get very banged up on the way home too (such as ripe peaches, berries, bananas or other fragile produce wouldn't make it back in good shape, cut up melon is a PITA if you don't have containers, etc.).

Extra water takes up space in the vehicle that may not exist depending on what else (clothes, gear, etc.) has to be brought back home. And unless it's YOUR cabin, you may not know the neighbors to give them the extras, and if it's a vacation rental those people will be in the same boat you are.

But you can leave the extra cookies with me any day of the week. I'll make room for those right up front! 

Pull all the leftovers out as well as a trash bin. Then one by one ask them if they plan to take it home. If they answer No, toss it in the trash right then and there. They will either stop you or let you carry on, but I guarantee they will get the message.

I know I personally am not good at planning exactly what food is needed for a certain number of people. If I was in charge of the burgers for example I would probably make 2 patties per person just in case someone wants more then one. How would I ration watermelon? I bring a watermelon to every cookout I go to. Sometimes I bring 1/2 a melon home, other times people are upset cause it all got eaten too fast. I always err on the side of having too much then not enough.
