Why won't my parents take me to get taco bell?

im home from college for the holidays and i'm hungry with no car here but my parents won't take me to get taco bell...there is not food in the house except cereal which i ate for breakfast and i want taco bell for dinner...so just curious why don't parents take their children to get taco bell when they're hungry like me...all i want is a burrito supreme, a Cinnamon twist and some triple layer nachos is that too much to ask for?
