If its a new client then I ALWAYS give them the benefit of the doubt first time providing they send me a cancellation text, a cancellation text is always appreciated. Its the ones who don't text you to cancel and don't show up and don't respond to my texts that get blocked cause that's obviously just a timewaster.
Sometimes things do happen where a client has to cancel, its the same with us. I am not in the habit of cancelling clients but it wasn't so long ago I had a client waiting in his car while I was putting on my stockings so we're talking about last minute here where I had 3 men at my door (2 plumbers and 1 of the factors) saying that the neighbours down stairs were flooded so they had to come in and check my bathroom, kitchen and boiler which meant I had to postpone my client by 10 mins or so (the water wasn't coming from me) but if the water was coming from me then I would have had to cancel at the very last second and it was hardly my fault.
So as I say, I always give a new client the benefit of the doubt, if they cancel again then I will be much more likely to then think they are at it and then block them.
When a client cancels, it is a pain in the arse but its life, its the rude timewasters you want to avoid.
