Let's call it a good news story that took an abrupt turn toward bad. It happened to Stella Gomes at a downtown restaurant.

Stella and her friend Margaret Webster had just finished a pair of tuna luncheon specials and were nearly back to their offices when it occurred to Stella that $34.45 was an awful lot to have paid for two plates of mere fish, special or not.

"So I called the restaurant and asked to speak to the manager," Stella writes. "When he quoted me the price, it was evident that I was overcharged."

Stella was about to ask the manager to adjust her American Express credit card slip, but she didn't have to. He happily volunteered to do it, apologizing all the while for what was apparently an error on the part of the waiter.

The manager's tone was so cheery that Stella figured it would be a piece of cake to obtain a corrected copy of the Amex charge slip. But when she dropped by the restaurant later that day to collect it, the manager turned surly. He didn't say so in so many words, but his attitude seemed to be: "What's the matter? Don't you trust me?"

But Stella would have been taking a foolish risk by failing to obtain a corrected receipt. Without it, she would have been defenseless if the manager had submitted the original bill to American Express. It was certainly her right to have a corrected copy -- and it would certainly have been good public relations for the manager to have handed Stella her corrected copy without nastiness.

As a result of what happened, Stella asks: "You wouldn't blame me if I never went back there, would you?" To which my answer is: I'd be surprised if Stella felt any other way.

Interestingly, an American Express spokesman says that Stella did not need to go back and seek her corrected receipt in person. If there is a discrepancy or a dispute on any Amex bill, "you must put it in writing to both the establishment and American Express," the spokesman said.

Should you confront a manager in person in this kind of situation? "That's a personal decision," the Amex spokesman said. But whether you do or not, you will still need to submit a letter to straighten out any arguments. So the face-to-face encounter is actually unnecessary.

It's too bad that tuna fish can cause such ill will. But the real tuna fish in this tale was the manager. He lost a customer simply because he turned a routine business transaction into something personal. For letting ego get in the way of reason, he deserved no less. CHILDREN'S HOSPITAL

If you watch the Redskins on television, I'm sure you've seen The Hogettes mugging for the cameras. They're the male zanies who dress up like female porkers -- gingham dresses, funny hats, hog noses, the whole bit.

A lot of people probably think these guys are long on beer consumption and short on community concern. Not so -- as a $95 Hogettes donation to our annual fund-raising campaign proves.

A big oink of thanks to all the guys. Now, if only the "Ettes" would improve the fortunes of a certain football team the way they've improved the fortunes of a certain hospital . . . .
