When the government were onto me, I told the manager this would be my last night tending bar.
I told all the customers, too, and gave them all one free cocktail on me, a "special". No more carefully listening to their stories and saving my gift for when the risk was worth it.
Didn't cure cancer that night, but it turned out that everyone _did_ need a special. I saw people crying into their drinks because a weight was lifted; hugging strangers; making earnest phone conversations.
