{
        "billposType": "article",
	   "articleNumber": "P000011",
           "articleAmount": "1",
           "articleName": "Spaghetti aglio olio e peperoncini",
           "articlePrice": "10.00",
           "articleTaxRate": "7.00",
           "articleComment": "Please bring the Parmesan in an extra cup.",
           "toppingItems": [
             {
             "billposType": "topping",
             "articleNumber": "T0002",
             "articleAmount": "2",
             "articleName": "Extra Parmesan",
             "articlePrice": "1.00",
