Holy Week Liturgy

Extra services.
Pastors have many sermons to prepare.

Some pastors have services to write too.  In congregations that don't use the liturgy, each week's service has to be invented afresh.  During Holy Week, that would be a lot of [unnecessary] work.

Some of us laymen yearn for Holy Week to come so that we can hear the same thing we heard last year.  And the year before.  And the year before.  The same liturgy.  The same hymns.  The same readings.  If you're reading the book, the same rites and pericopes don't get stale, even if they've been used for hundreds of years ... because those words are the life of the world.
