Unless you eat a lot of take out, you know from experience that pots and pans at the end of a meal don't do themselves -- you need to roll up your sleeves and tackle the job.
It's no different at the monastery, except our pots and pans tend to be larger (our usual number for an ordinary meals is about 20 including volunteers). Add a retreat group -- or two, and the number can climb to 60, 70, 80 or more! So it definitely can be a bigger task.
Work in the monastery isn't viewed so much as a "job to be done", although it is that as well. We try, sometimes better and sometimes needing improvement, to see every task as a manifestation of our love for God and for our neighbor.
