I will book from you. ONCE.
I think the scenario here is the moller called up and give a reason for not coming for the job.
Not a no-show scenario. Just that some photographer think that the excuse is absurd (and my point is who are we to judge?).
We often call in sick on the morning. Do we force ourself to work and had the boss sent us home after that? What if we spread the virus to our colleague? In this case, the photographers.
I am sure we are disappointed when a shoot is cancelled as we make time for it. It's any better to be told of the cancellation face to face as compare to a phone-call or sms?
