A mother had three daughters

A mother had three daughters and, on each daughter’s wedding, she tells each one to write back about their married life.
To avoid possible embarrassment to their new husbands by openly discussing their love lives, the mother and daughters agree to use newspaper advertisements as a “code” to let the mother know how their love lives are going.
The first one gets married and the second day the letter arrives with a single message, simply: ” MAXWEEL COFFEE HOUSE”.
Mother got the newspaper and checked the maxwellcoffee house advertisement, and it says: “Satisfaction to the last drop…” so, mother is happy.
Then the second daughter gets married. After a week, there was a message that read: “ROTHMAN`S MATTRESSES”.
So, the mother looks at the Rothman`s Mattresses ad, and it says: “FULL SIZE, KING SIZE”. And Mother is happy.
Then it was the third one’s wedding. Mother was anxious.
After four weeks came the message: “SAUDI AIRLINES”.
And mother looks in to the Saudia airlines ad, but this time she fainted.
The ad reads:” THREE TIMES A DAY, SEVEN DAYES A WEEK, BOTH WAYS.”
