This is the shocking moment a parking warden issued a ticket to an ambulance parked on double yellow lines - while paramedics took their first break in eight hours. The workers for North West Ambulance Service parked up outside a supermarket while on shift to nip in for some water to drink. But a video shows the warden issuing a ticket while the emergency worker pleads "I've had nothing to drink and nothing to eat". The heated exchange was filmed by outraged passerby Ian French, who claims the cap-wearing attendant told him he was "proud" of issuing the ticket.
