Mrs. Donoghue won a compensation claim against the manufacturer of ginger beer after she suffered harm from drinking the product, which contained a decomposed snail. The court ruled that the manufacturer was not liable for negligence as they had no duty to care for customers. In another case, Bill is liable for negligence and XYZ Dairies can be held vicariously liable for his careless driving, which injured someone. The concept of vicarious liability applies when there is a legal relationship between the defendant (employer) and the person who committed the wrong (employee). Additionally, businesses can be held responsible for 'wrongs' committed by their employees during working hours or within business premises.
