Crewe Station - Car park

Short stay parking at \CRewe Station is limited to 20 mins-free. I took an 85 year old person to buy a ticket and catch a train. With the delays caused by the traffic/pedestrian crossing-each way and the distance to the platform it was almost impossible to limit the time to 20 mins. The penalty for failure is £10 per hour. The time limit should be increased to at least 30 minutes. I challenge British Rail employees to complete the task within 20 minutes
