Researchers in the United Kingdom compiled a list of the top twenty ridiculous complaints lodged by travelers with their travel agent.
I recommend the reading the whole list.
But, my top three are:
The gentleman who felt the aroused elephant he saw in Africa made him feel inadequate.
The traveler who was upset that the three bedroom suites were larger than his one bedroom.
And, the parent who complained that they had not been properly warned that there would be fish in the sea.
Hat tip to Boing Boing for the link.
