I'm curious to know how the parking attendant is supposed to kn ow that you are a long standing customer who spends thousands of pounds in the shop. You were warned. you ignored the warning. You should pay up. If you don't want a parking faff, shop online. My daughter has a toddler and a baby and has, before now, not been able to find a parent and baby space which is ridiculous. I don't think the manager should have cancelled your ticket. What is the point of notices and warnings if drivers can ignore them?
