Earlier quoted context omitted.
Out of curiosity, do you feel that 10 years of loyal service should not be rewarded with any kind of raise at all? Even if he wasn't earning much more than 8 or 9 dollars an hour even then, but it probably would mean quite a bit for someone in that situation. With inflation, he was actually being paid less 10 years later.
The real question you should be asking is if his pay is so low, why didn't he get another job? There's a reason he stayed. Did he deserve it? Maybe, the article mentioned he started out as a waiter and (moved up?) to dishwasher. Maybe dishwasher paid more, who knows. But my whole point is a manager in a restaurant has less control over raises than you seem to suggest.
I think it was the roommate, Rogers, who had been a waiter.
