A concerned mother

A mother had three daughters and on their wedding she asked each one of them to write home and tell her about their married life.
The first wrote back on the second day. The letter arrived with a single message, "Maxwell House Coffee". The Mother is confused but finally noticed a Maxwellcoffee ad, and it said;
"....satisfaction to the last drop..." So, Mother was happy.
Then the second daughter got married and after a week she sent home her reply. The message read; "Rothmans". So the Mother looks For the Rothmans ad, and it says;"LIFE SIZE, KING SIZE". And Mother was happy.
Then it was the third one's wedding. Mother was anxious. It took 4 weeks for a message to come through. When it did the message was simply "BRITISH AIRWAYS".
Mother was so concerned. She frantically went through all the newspapers at home
looking for a BA ad. She found one and fainted. The ad read: "TWO TIMES A DAY, SEVEN DAYS A WEEK, BOTH WAYS"
