I would have difficulty too. My eyesight is not that great and having to look down at the floor lowers the light available to see color and pattern. Plus, I cannot get down and back up any more.
I would suggest a letter or phone call to the owner and tell them what the problem is with the displays. If enough complain, maybe some changes will be made. I cannot imagine having fabric down close to the floor unless there are mulitple levels and then it often can be overlooked.
I have also mentioned to stores that having things on the high top shelves that short people might want is not a good idea either. We have a discount bookstore and the craft magazines where even too high to reach without a rolling stool. Not a safe situation with an older population.
