However, one warden in Shirley, West Midlands, has provoked outrage after parking on a double yellow line before walking off to issue tickets to other drivers.
Despite being challenged by pedestrians over his behaviour, the Solihull Council employee then climbed back into his unmarked car and drove off.
Witnesses say the man pulled on to the double yellow lines at around at around 8.50am yesterday.
He spent the next 15 minutes waking around nearby streets, and handed out at least one parking ticket.
Leon Kennedy, 31, was walking to work at the time and asked the traffic warden why he was parked on double yellow lines.
