Manchester Airport

On 28/8/19 we were dropped off at terminal 1 drop off zone by a friend, My wife and I both have mobility issues, Our blue badge was prominently displayed in the windscreen, we couldn't find any assistance in the area but had checked online previously which advised to display the blue badge in the windscreen and we had 10 minutes grace and any problems we were to ask a "parking marshal" who would sort out a disk for exiting the area. No marshal available so our friend went to exit the area with the badge prominently displayed but was not allowed to exit without paying £4 for under 10 minutes for dropping off Blue badge holders, Outrageous!!!!!!!!
