I'm feeling the urge to park my food truck on 2nd Street even though I don't have a permit.
Why do you want to park your food truck on 2nd street without a permit?
The permit is expensive and I don't want to buy one because it will reduce my profit.
It's wrong to operate your food truck on a street without a permit. Every food truck operator needs to buy a permit and if you don't you are breaking the law. You could be arrested and your food truck seized if you park it illegally.
It's legal, as long as I'm not hurting people it doesn't matter.
It's not legal though, you don't have a permit in your old face fines. It's not worth in the long run because any profit you make will be taken away by the fines that you face.
