«Manuel, a waiter played by Andrew Sachs, is a well-meaning but disorganised and confused Spaniard from Barcelona with a poor grasp of the English language and customs.»
In the Spainsh translation of Fawlty Towers Manuel was Italian (that way us, poor Spaniards, will not be embarrassed by watching one of us strugling xD) and I suspect that in other countries they changed his nationality too.
