Do you let your neighbors throw something on?

Hey all, got a question. When you go out and fire up your smokers for a long smoke...say pork shoulders or a brisket...and you have extra room in your smoker, do you every invite your neighbors to throw something in?

When I am grilling, I usually take up most of my grill because I am usually cooking for 3-5 days in a single cook, but in the smokers I am looking at and what I would normally put in for a week, I will have a significant amount of extra room. It seems a waste of fuel if I have that much spare room.

Not looking for money for the fuel, asking them to bring a cold beverage, or anything, just a "hey, if you got something you want to put in the smoker, I am planning on a X hour cook on Saturday" type of deal. Come on over anytime after 6 am and feel free to throw in it so long as it's done by 7pm" type of thing.

Big thing I am worried about is food safety, and a little bit of liability. What happens if they burn themselves touching something hot. What happens if someone gets sick because their meat was undercooked when they pulled it, but it was cooked on my equipment? They could claim that the drippings from my food was what made them sick for instance. I cook to a measured temp, not a x hours/pound type of formula, so if I have to cook mine a bit longer, that's fine with me, but more worried about them.

Not looking for the lawyer answer, just your own experiences. Is it worth it, or just let them buy their own dang smokers?

Thanks

Honestly, if I went up to a stranger at a tailgate and asked to use their grill due to a problem in my setup. I would probably insist on overpaying for gas too.

You did a nice thing and you probably saved his bacon (metaphorically) because those are probably the only things his kids would eat...

I think I will just do my own stuff, but if my neighbors comment/ask about it (I've had my HOA president make snide comments about the smell of woodsmoke some days), I just tell them to come over and throw something in.
