According to the Subway Ireland website, the chain's six-inch and footlong subs are available on six different kinds of bread.And, according to the country's Supreme Court, all six varieties are too sugary to legally be called "bread" at all. .The case started when a franchise owner challenged the tax authorities' decision not to issue a tax refund.The argument was that since the sandwiches use bread, they are a "staple food" and shouldn't be taxed.But the five Supreme Court judges countered by suggesting that those sandwiches aren't served on "bread.".The judges ruled that Subway's bread is not a staple food because its sugar content is 10% of the weight of the flour.The Value-Added Tax Act of 1972 stipulates that sugar cannot add more than 2% of the weight of the flour.For now, we can still call it "bread" in the USA
