AIBU to expect that a holiday company (say Thomas Cook) should not classify a person age 10 as an adult? I was happily booking next years holiday when I noticed the price had shot up. Not a few pounds, but the cost increased by 20%. I put my specs on, and there it was in the tiny small print, that an adult is considered to be 10 years or more. This strikes me as being really unfair and misleading. Surely at age 10, a child cannot reasonably be considered an adult? A further flick through the brochure and I found some hotels classify an adult as age 7 or over. AIBU?
