In the expression "free excuses", qualifies the play of the excuse by the taker on a blank trick, or on a trick impossible to win, for example on the lead of the 21.
This term can be used when a product contains no amount of, or only trivial or "physiologically inconsequential" amounts of, one or more of these components: fat, saturated fat, cholesterol, sodium, sugars, and calories. For example, "calorie free" means fewer than 5 calories per serving and "sugar-free" and "fat-free" both mean less than 0.5g per serving. Synonyms for "free" include "without", "no", "zero", "negligible source of", and "dietarily insignificant source of". Because it may be virtually impossible to measure below a certain amount, the regulations allow a fat-free claim on foods with less than 0.5g of fat per serving. An amount that they argue is physiologically insignificant even if a person eats several servings. Consumers need to be aware that the food isn't truly "fat-free" and fat calories may add up if enough of the food is eaten.
