Two per day is plenty...... For Theming Thursday!
During the rest of the week when the demand is not as high I would still reduce it, but to 4 or 5.
I agree with the others that 10 per person per day is just excessive.
But let us acknowlege how difficult it is to manage such a task and applaud admin for the process that is in place. It can be easy to not notice all the hard work and dedication that goes on behind the scenes. So let's not forget their contributions!
