No, spelling "their" instead of "they're/there" is a MISTAKE. Not a typo. Typo is when a letter is missing in a word, or if it is misplaced. Like "hlelo". Plus, it's "plain", not "plane". I'm not trying to be an ass, but just letting you know.
Lol nice baker, who actually writes the words "underneath that" when a person orders what to be written on a cake
What's REALLY HILARIOUS is that there should be a comma after the word 'that'!!! They forgot to put the comma in!!!!!!!111
