I think you must be a nice person, or people wouldn't give you things no matter how frugal you look.
40 years ago, back in miniskirt days, I had guys offering me little perks like touching up the dings in my car's paint job, that sort of thing, when I wore my knee-high leather boots. I wasn't cute, but had really nice legs.
Now that I'm old and pathetic I get offered advice (as a first-time homeowner I'm demonstrably ignorant) and handyman services, yardwork, etc, that they think I can't handle. I'm living with a lot of retired people with time on their hands, and right after I moved in I had a knee replacement, so everybody got the idea I was helpless. And I sorta was, but it took me a while to learn to accept help. I have always tried to be independent, but I seem to be playing the Southern belle here - "I just don't know what to do about this shaky railing..." I have three neighbors wanting to trim my rosebushes for me, and when I have the other knee replacement I won't be able to fend them off anymore; they'll just have to divide the work up.
I'm blessed with a kind and generous friend named Antonia - she started as an employee in our business, and when my husband had his long illness and could do less and less at work, she just took over more and more, til she was pretty much running the production, and driving us around, helping with shopping, and so forth. After both he and the business were gone, she helped me find this mobile home and pack up and move everything. One reason we picked this place was that her new job is just up the highway.
Her new employer had been one of our customers so I get invited to their Christmas parties, and whenever they have an employee birthday party, they give her a plate to bring home to me! Also, they clear out the fridge every Friday and load her up with anything still good. Since I've always liked being creative with leftovers...
The owners there like to eat well, and they seem to be trying to educate the workers' palates; most of the people like to eat familiar things, they like what they like, darnit, so I get all this food they are not adventurous enough to eat, like Thai take-out, porterhouse steaks cooked rare, salads with weird-looking gourmet greens in them, and similar good stuff. It's fun! I get altogether too much birthday cake, though.
Tonia also has some friends who own a resale shop which they stock with goods auctioned off by public-storage places; since most of their clientele don't read English handily, they were just discarding all the books! So now they save them all for me - free reads and then I trade, donate, or Freecycle them.
You're lucky to have the fish and milk lady! I'm sure you deserve these offerings fully as much as I do - (smile). She thinks you're a good neighbor, not just that you're poor. You probably do things for her, too, and it all comes around again. It's a small-town thing, too (I'm assuming you're not in a large city); where I grew up people were always passing their garden veggies around the neighborhood, and the men would go hunting and divvy up the deer or occasional moose.
Darn, no-one gives me octopus, though; have to buy my own.
