If you've ever wondered where you sit on the list of biggest complainers, then now is your chance to find out.

Uswitch described on their website how they came up with the methodology for this research:
"To find out the names of the most common complainer, first, we gathered a list of the world's biggest tourist attractions, using their Trip Advisor pages to filter for 'poor' and 'terrible' reviews," the company wrote. "We then collected the names of the people who wrote these reviews for the first 50 pages, focusing on those who wrote their reviews in English.
"In order to find out how much time was spent negatively reviewing the attractions we found out the average word count of the poor and terrible attraction reviews and divided this by the average number of words typed per minute."
