Footnote Nonsense

I was reading a flyer for some real estate agent advertising a condo for sale, and at the bottom of the page there was a footnote marked with an asterisk. The footnote read: * Information believed to be reliable, but not guaranteed. So I started to wonder what information, exactly, was the agent referring to? Was he saying the square footage was reliable, but not guaranteed? Or perhaps the number of bathrooms? Maybe the lighting isn't actually recessed? Is the address of the place wrong? Or maybe it meant that the realtor's information was not guaranteed. Could it be his phone number? His name? Curious to find out exactly what information the footnote was referring to, I scoured the flyer to find the matching asterisk (*), but it was to no avail. Nowhere on the sheet could I find the initial reference to the footnote. This is one of my pet peeves.‡ If you're going to pretend to have a footnote, and are even going to mark it with an * or a †, then it's got to have a matching point of reference in the actual document. I can't even count the number of times I've found orphaned footnotes at the bottom of the page, with no corresponding reference in the document. It's very bad form. The only worse footnoting crime is to have a footnote marker in the body of the document and then forget to include the actual footnote or endnote at the bottom of the page or the end of the document. I've seen this happen more than once in the super-fine-print user agreements that credit card companies send out. Somehow, though, I wouldn't be surprised if those footnotes were "forgotten" intentionally. ‡ See? This is how you footnote. It's easy!
