okay , not problem . would you like to travel by train or taxi ? where are you departing from ? is there a time you need to leave or arrive by ? there are 2 trains you can take on monday , either the 22:01 arrive 23:01 or the 23:01 arrive 24:01 . which train do you prefer ?

would you like me to book the 22:01 ?
