Big Mac Sauce is delivered to McDonald’s restaurants in sealed canisters designed by Sealright, from which it is meant to be directly dispensed using a special calibrated “sauce gun” that dispenses a specified amount of the sauce for each pull of the trigger. Its design is similar to a caulking gun.
In Boston and New York City, a “brownstone” is understood to be a terraced house (rowhouse) clad in brownstone. These brownstone apartments typically have stairways which lead from the sidewalk to a second-floor apartment entrance, a design originally intended to avoid bringing in the mud and horse droppings commonly found at street level, a problem that existed when these apartments were built and horses roamed the streets.
