It can't rain all the time
Crabs in the Maldives
(For a year I worked in the Maldives. For those who don't know, these are lots of beautiful islands made of sand a coral and surrounded by amazing turquoise seas. On my first ever day this conversation took place)
Customer: I wish to go home
Me: I'm sorry to hear that, may I ask why.
Customer: Crabs! I am petrified of crabs!! There are crabs everywhere!
Me: You do realise you are on an island made of sand and crabs live in sand.
Customer: Well how am I supposed to know that crabs like sand. The travel agent never mentioned anything about crabs.
(2 days later the customer paid almost £2000 to fly home 3 days into her 2 week holiday. Her holiday originally cost her £4000!)
