Max 3 hours stay! Update to the rules on this parking at Asda. The new signs say 'customers only, 3 hours max.' I just paid a £40 fine for staying for 4 hours before noticing the new signs, stayed there a week before and no problem. Fustrating as there is plenty of space in this car park, so no need to introduce this new rule. Will need to look for alternative place to park next time.
