The 2 Aldi stores local to me, Hastings and Bexhill, both have delivery bays that use the car park entrance, at both stores crosshatched no parking areas are clearly marked to give the delivery guys room to reverse in but there is invariably a car parked on the crosshatching. The Bexhill store is blind side reverse but the Hastings store is ok (If only some idiot was not parked on the crosshatching)
IMHO no supermarket should ever be designed with the delivery bay accessed through the public car parking area!
