Is your marketing message saying what you think.

As you see on the attached photo. Burger King wanted to announce that the whopper was 50yrs old.  What they communicated however, was that one of there burgers had ben sitting around for 50 years.  What a difference a little punctuation makes.

This brings home a time tested truism to always have a proofreader look at your public facing materials even somehting as simple as this.  Could save you some time and embarrassment.
