In Boston, we do not give directions in terms of Tim Horton's, whatever that is. We use Dunkin Donuts. Example: Follow Comm ave, past two Dunkin Donuts. Turn right on Mass Ave, and continue
past a third Dunkin Donuts on the right. Turn left on Harrison Ave, just past Dunkin Donuts, and you'll arrive at Boston Medical center. See?

Now, as for asking for directions, you all know that doing so is a violation of man law, and it simply something we just don't do.
