Really? They are catching money from everything. I think the maintance fee is high enough to pay for this temporary card no?
Do you call 20 pounds a small charge when people are told to it was for free?
If you have a family of 4 persons (2 children) going on beach holiday for 2 weeks, the total cost is 80 pounds a day x 14 = 1120 pounds = 145 euro!!! I do not call this small money
