We do a large export trade (that is,the firm does), and there are often sample bottles lying in the office.There was a bottle of tonic port,which had been there for some time,and the manager told the head that he could have it if he liked. Later in the day the head clerk said that if a bottle of tonic port was any use to me, I might take it home.He said he had just opened it and it and tasted it,because he did not like to give anything away until he knew if it was all right.
