School bags and shops

How annoying is it when you walk into a shop and there are school bags all over the place. Yesterday I had DD4 in the stroller, two kids in front of me, one of them swung their bag off their shoulder and hit an elderly lady in the arm then as we walk into the shop the other boy drops his bag right in front of the stroller. I called out to him and asked nicely to please move your bag, he comes back picks it up and throws it in the corner. I understand they can't bring their bags into the shop but maybe a set area for them, they have bags lined at the front on the footpath then you have to dodge them once your'e in. Just annoying that's all.
