I suggested that they should stay at "bed and breakfast" houses, because this kind of accommodation gives a foreign visitor a good chance to speak English with the family. My friends listened to my advice, but they came back with some funny stories.
"We didn’t stay at bed and breakfast houses," they said, "because we found that most families were away on holiday. "

Then my friends went to house where the sign said " NO VACANCIES", because they thought this meant the people who owned the house were not away o
A. didn’t really want any more coffee
