What happens from a ML's persepctive is, a punter will make a booking for say 30 mins at 11am. Within the space of 5 minutes, 3 other punters want to come at 11am too. So the ML has to put off those other 3 punters. Then if the original 11am punter cancels, by the time she contacts the other 3, it's either too late or they have made a booking elsewhere. So for her. the loss is significant. And hence the shitty disposotion that follows
