One web designer has found a seemingly perfect way to get revenge on a client who she says hasn't paid its bill.

Every designer or artist has at least one client who refuses to pay their invoices on time. One web designer has found a way to get revenge on a client who hasn't paid their bill, as she appears to have replaced two of their sites (screengrab above) with a copy of the unpaid invoice.

The invoice is to the Caribbean Dutch Pot Restaurant in Gwynn Oak, a suburb of Baltimore, Maryland in the US. It's for a website, logo and marketing campaign for the restaurant's Baltimore Reggae Jerk Festival last summer at the nearby Woodlawn Memorial Park. Both the Baltimore Reggae Jerk Festival and Carribean Dutch Pot Restaurant websites have been replaced by the invoice. A Facebook page for the festival still exists, so it appears that this isn't just a very funny hoax. The restaurant is listed on TripAdvisor, though the single review is rather negative.

The site is registered to a Julie Williamson in Baltimore. We've contacted her to confirm the story and find out more. We will update this story when she responds.
