When Devs Moonlight At McDonald's

When you ask for "McDouble, only ketchup" and get a sad bun with just ketchup because the fast food worker parsed your request like a poorly written function parameter. Classic case of ambiguous syntax in human-to-human interfaces. Should've used proper operator precedence: (McDouble) && (only ketchup) instead of McDouble && (only ketchup). The compiler at McDonald's took the literal interpretation.
