So the comment about COUNTING tickets then and allocating correctly to those already booked passed you by.
My ten year old can count. I could give her a list of names and say allocate this batch to these names/numbers.
And I wouldnt have to train her. Oh and she can answer the phone.
I cant because child labour is against the law. But I would employ a fit 18 year old to do it.
5 years too old to write the addresses on envelopes as well.
