The original owner and founder of my present employer (now retired) is an entrepreneur, and a classic Type A personality. Hard driven, and demanding as hell, but as demanding of himself as anyone else, and under it all, a decent human being. (Only Type A I've ever known who, when confronted with evidence he'd made a mistake, would just say, "You're right, I'm wrong, now go fix it." Mind you, he'd never apologize, but he'd admit he was wrong.) Let's call him Bill (because that's not his name).
"You'll be OK. Turds float."
I was truly surprised he wasn't tossed out of the store on the spot, even if he did only have a day or so left. Bill had mellowed as he got older. Or maybe he'd gotten rich enough to have a sense of humor surgically implanted.
But speaking of Bill, there was the day that the store manager (not Fred) in the fishbowl (the store where the corporate office is) got a comment from a customer about an employee who smelled of alcohol. The manager, very concerned, asked which one, and the customer pointed out Bill. "Well, you see, he's the owner, so he's allowed to do that." Customer thought that was perfectly reasonable. (Bill is the sort of guy who is absolutely incapable of walking by a customer who wants to give us money, and not stopping to see if he can convince them to give us more, whether he had a shot before he headed home or not.)
And then there's Abe. Abe has true leadership skills, and his people generally like and respect him. But he's one of those people who can't turn a computer on and off without help, and literally can't read an error message off a monitor screen in front of him because "I don't know anything about computers." (I know this from experience - multiple times) Completely helpless with computers. So he was transferred to a different store. The morning he took over, he tries to ring up a sale, and corporate had forgotten to add his logon to the new store. Phone call, complete panic, and I didn't have the security at the time to fix it. "Have a cashier sign in for you, and <guy who can fix it> will be here shortly." Civilization ending catastrophe averted. A little while later, the receipt printer runs out of paper, and we're in the middle of cash register upgrades, and he hasn't seen the new model before that day. Another phone call, complete panic again. "Have a cashier show you how, they've done it a hundred times." (The new printers, it's a matter of open the cover, drop in the paper, close the cover. No feeding paper through slots you can't see, like the old ones.) Catastrophe averted again.
