SIR – One example of a subtle message being more effective than a loud government health warning is found in New York ("None so deaf as those that will not hear", June 23rd). Bars across the city display a plaque with the standard boilerplate that "Alcohol during pregnancy causes birth defects." In one establishment the message has been rendered brutally effective by a patron who has scrawled underneath, "Just look around."
