Yeah, what some people are describing in this thread is just as much a “boycott” as not showing up for work is “going on strike.”
As I understand it, a boycott is an organized refusal to patronize a business until they agree to change some policy or practice that the boycotters find unjust or offensive.
As for boycotts for non-service reasons, Chic-fil-A and Hobby Lobby, but since I very seldom need what they offer, it’s no strain.
Refusing to do business with them again: Applebee’s restaurant and Alamo Rent-a-Car. Don’t screw with me or lose my business forever.
Local business? Can’t think of any.

Is there a term for a personal boycott?
But for the OP. I’m sure that everyone has a list of pizza chain restaurants that will never see their business.
There’s also a restaurant chain where I have always had great service and food when I was there in other towns so I was thrilled when I found out we were getting one locally. I’ve given them three chances and the food has been crap every time so they’re on the no-go list until there’s a change of management.
Finally there’s a gas station that’s not in a bad part of town, but once or twice a year there’s a news article about a fight breaking out there and one time somebody was shot. I’m gonna avoid that potential drama.
Apparently “boycott”
Not really. I’ve never eaten at Chick-Fil-A, but not because I don’t agree with their politics (I don’t), but I seem to only ever be around one on Sunday, when they’re not open.
A local pub once got my steak wrong twice. I haven’t eaten or drunk their since.
Local bar/restaurant, several years ago. Mr. Athena and I had been doing some shopping, and decided on a whim to stop at this place for an early dinner. Mr. Athena was carrying a grocery bag full of produce we’d just purchased a few doors down at the local veggy market.
We walked in, and it was pretty packed, but there were 4 barstools at the end of the bar. We sat down in two and ordered a couple beers, then Mr. Athena was like “Hey, this is stupid, we’re parked across the street, I’m gonna take this bag to the car so I don’t have to hassle with it here under the bar.” So he does.
Right about then, it started raining. This place has a patio, and there were 3 folks out there eating. They ran in, and one of the waitresses looked around for a place for them to sit and eat. She came and asked me to move down so they could sit in the empty seats.
I politely told her one of the stools was my husband’s. She said “We have a policy against holding seats for folks who aren’t here.” I told her he WAS here, he’d just ran across the street to our car for a moment.
She repeated herself. I couldn’t believe it. I pushed back a bit, she told me to move down again.
At that point I just gathered up my stuff, left the 2 beers on the bar and headed out. Mr. Athena was walking in the door at the same time and was like 
I told him what went on, and we’ve never been back.
I live in a one-horse town where there isn’t much to speak of in the way of business, but nonetheless there are three places in this town that I actively refuse to do business at. One is a junk resale shop with pro-Trump propaganda in the windows - although to be fair, I wouldn’t shop at a junk resale shop regardless of what they had in their windows. Ditto for the sign manufacturer that I’m “boycotting” - I just don’t need any signs made. The other place that I’m boycotting is this town’s one sit-down restaurant. Their food is just atrocious.
The local Buffalo Wild Wings because one time I filled out the ‘anonymous’ survey on the back of the receipt and didn’t give them the highest marks and, the next time I went in, the manager confronted me about it.
Wow.
Please tell me your response was to ask for as many blank surveys as he had, then proceeded to fill them out in front of him, giving the lowest rating for everything.
Just so you know, that doesn’t happen often. I’ve worked in food for quite a long time, and i’ve never seen anyone deliberatly make food unsafe.
Say, “Well, I was willing to give you another chance to improve your survey scores, but I suppose instead I will just be talking to your district manager.”
IIRC, it was an online thing and you used the code on the receipt. Somehow it must attach to the receipt number and thus the credit card used for payment or something. The manager was a she. She may have even been the owner. She didn’t have a uniform shirt on or anything so I had no idea who this person talking to me was but I figured it out.
It’s just easier not to go back. It’s not like there aren’t other chicken choices in town. 
Chick-fil-A is the only one I can think of where we have no complaint about their food, but are not fond of their anti-gay corporate behaviors. So we don’t eat there.
Otherwise it’s the usual bunch of misfit businesses that are unclean, continuously and conspicuously fuck things up, and/or have bad customer service. Typically I seek out competitors.
Three restaurants, all locally owned;
One: gave an average review on yelp and was told by the chef owner I was a terrible person and never come in again.
Two: complained about the food and drink, manager told me not his problem.
Three: filthy place
These have been interesting responses!
There’s a local pizza place that I love, even though my first experience there had problems.
I called in an order and arrived to pick it up. The young lady at the counter was dismayed, she’d taken my order and somehow didn’t turn it in. I work in food service and know that sometimes stuff happens, so I said I’d wait. She darted into the back and came out with the manager. He said they were going to give me the pizza for free, and also a coupon for another free pizza. Whoa! I was happy to agree. So it’s how a mistake is handled that matters, not just that a mistake was made.
You went back after the first time?
I won’t deal with CVS anymore because their local store was completely incompetent at handling my prescriptions, even after multiple in-store conversations about it. In fact, after transfering all of my active prescriptions to another retailer, I got a text yesterday about a prescription that I had told them on each of the previous three months that I was no longer taking and to remove it from my list. If they can’t manage to do that much, fuck 'em. They can’t be trusted.
