I've been weeding out deadbeats this week and I had more than I realized. I started keeping records and found I had a half dozen who order long dishes but never fill them. I've lost two long dishes (went to counter). So I can understand the occasional order not getting filled. But each of those I unfriended failed to deliver three long dishes I had ordered after delivering similar dishes (often just a different variation on the same base recipe). Each. They must be burning or serving the bulk of their cooking…or they're simple deadbeats who order but don't reciprocate.
One person who states on GC they won't fill orders over 18 hours never-the-less orders them from me.
Another I unfriended after a week of not one delivery and nearly daily orders actually tried to friend me again.
On the flip side, I have some really wonderful friends who seem to always or close to always come through. I feel good about cooking long dishes for them though it's a strain on my zombies and limits my raids, because I know they are willing to do the same for me. I make an effort to look through my fridge for dishes they don't have when I visit and leave them as gifts, as a sort of thank you.
Most fall somewhere in between, as you would expect. As I said, I've lost dishes too, so it's okay if they don't always come through so long as they don't seem to be just using me.
So I wiped out a quarter of my friends list and am still waiting on two more to see if they manage to deliver any of three orders I've placed this week before tossing them too.
