New Kid in Town Mistakes

So I moved to this new city two weeks ago and still getting used to things. Yesterday, I was on my way back home from the grocery store and thought I was taking a shortcut through what looked like an office park but turned out to be some sort of business district with actual working offices. Everyone was staring at me because I was carrying bags of food down the sidewalk while they were all in suits rushing past me. Then, to top it off, someone even yelled something that sounded like 'You don't belong here!' and my face went beet red. Oops.
