You said he "was attacked once".  I don't know Wisconsin law, but in PA you can use deadly force when someone physically attacks you.  I guarantee the attackers are young, strong Black men and the store owner is anything but.  Certainly disparity of force from a bodily threatening mob.

At the very least he could use pepper spray or Wasp spray as a deterrent.

Last night my department chair sent around an email saying the Dean needs to know how many of us are going to encourage our classes to participate in the so-called Climate Strike next Friday. That weekend is Homecoming and is expected to be the biggest in the institution's history (it's our bicentennial year). He wants to know so that he can defend - or tout - faculty who participate, depending on which alumni he is talking to.

My physics class has an exam that day. Needless to say I'm not participating, and if any of my students do, they get an F.

How come you don't make tears when you breath through your mouth? I don't understand.

Every few days I download all our transactions and go through them one by one, and assign categories to them (groceries, home maintenance, auto fuel, hobbies, date night, etc.) and that’s how I caught the Netflix after only one charge and even then I might have missed it because we also have a Netflix account. My eye would not have seen it as abnormal unless it were close in time to our normal charge. However it was on the wrong card. That was the big flag.

I never figure out where the card got compromised but I suspect the duplicate readers at gas pumps or the grocery store, and waiters and waitresses, and even doctor office staff, but also online purchases. I try to limit my online purchases to Amazon but if they don’t have something then my card gets in some other database. They’re being hacked all the time.

Back when I played World of Warcraft my card got compromised, and three months after I got a new card, that one was compromised and I suspected WoW and called them up, they denied it, said their system was secure but I think they were lying. If companies have a breach they don’t always tell you. JC Penney had a breach and didn’t tell customers until 3 years later.  I had a card with them back then and was part of that incident.

My mom’s pest control guy got the ransomware. They hacked his machine and got all his data and locked him out. Fortunately he did not have mom’s credit card info, only her name and address but it meant he couldn’t mail her the invoice for several months after he treated her house. They wanted $5000 iirc so he didn’t pay but recreated his business data and set up a much more secure system.

Any small business you give your card to could have bad security and even the big companies get hacked. I now accept that’s its normal on a regular basis. Thank God we aren’t liable for the fraudulent charges. But the credit card companies are and I’m sure the cost is passed through to us somehow. These criminals are scum.
