Sorry if I wasn't more clear there Monster, I didn't want to lump everyone together, and I totally agree that the blatant time wasters have absolutely no intention of showing up.
I was just saying that with all the time wasters that the ladies seem to get in their average day, combined with people running late or inadvertently having to no-show/cancel because of unforseen circumstances, the ladies can have more than half of their day wasted, and it can understandably be difficult sometimes for the ladies to distinguish between who the blatant timewasters are and the genuine client that's running late or had to no-show/cancel for circumstances beyond his control. As far as the ladies could be concerned, they've had their time wasted either way, and not know who was just messing them about and who had the genuine intention to show-up.
