Also this question seems a bit ridiculous: "I can decide the time I start and be reasonably confident of having work to undertake" If you're driving a cab, you work when people need cabs. If you're delivering food, you work during times of the day people are ordering food. This is the nature of these jobs. Does an icecream truck owner get to decide to work during colder or rainy weather because that's what he prefers? Of course not; he has to work at times and places where people are likely to purchase ice cream. It hardly seems reasonable to blame deliveroo for the fact that people tend to cluster food ordering during one or two periods of the day.
