Someone was confused about the meaning of the word “there” and the word “their” in a sentence.

This poster is in the Rainbow Center.  I don’t know who corrected the misprint, as it was not me.

This other poster is in King Manor.  I didn’t make these posters.  I’m only pointing out the typo in the sentence.  The one who created this poster should have learned the difference between “there” and “their” while attending elementary school.
