I think the case that I really think took the biscuit, the female barrister who got struck off who'd been dining and dashing. On one occasion she ordered food from some Deliveroo type organisation, and when the food was delivered, told the guy she'd already paid, she hadn't, shut the door in his face once he'd handed over the meal. Then that poor person had whatever she owed deducted from his money, how appallingly mean
Although it probably wasn't Deliveroo, I've been around my son when he's placed such an order and I'm pretty sure he gave his credit card details at that time.
