"Daughters' Marriages" joke

A Mother had three daughters and on their weddings, she tells each one of them
to write back about their marriage life.
And the first one gets married. The second day the letter arrives with a single
message... simply, "Maxwell Coffeehouse." Mother got confused and finally
noticed in a Maxwell, and it says, "Satisfaction to the last drop..." So, Mother
is happy.
Then the second daughter gets married. Only after a week was there a message
that reads, "Rothmans." So the Mother looks into the Rothmans ad, and it says,
"Life Size, King Size." And Mother is happy.
Then it was the third one's wedding. Mother was anxious. Only after four weeks
came the message, "British Airways." And Mother looks into the BA ad, but this
time she fainted. The ad reads, "Two times a day, four times a week, both ways."
