On the whole, people prefer the pay at the start routine so that they don't need to keep remembering or being reminded. Limits the remembering and reminding I have to do too, and makes the job even more enjoyable.

Agreed, students push the teacher to work harder, practice and research more, and improve their skills.

One downside to what I do is the commute past the fridge every couple of hours.

Peace, Mooh.
