First question, did your mother/the first aider make an entry in the accident book at the store, or some other record of the accident? This might be critical if you are going to put in a claim as it will be evidence that it really happened (not that I doubt you, but liability insurance looks at it from many angles). Take a photo of the sleeping policeman now, before they have a chance to improve on its visibility (it can be said that if improvements were made after an accident, then that can be taken into account when considering a claim, as the location wasn't safe in the first place). The store probably won't get in touch, in insurance law it can be considered an admission of liability if they express any regret about the accident (or it was in my day). If the store can be proved negligent then yes you should claim - and there are plenty of no win, no fee, claims companies out there eager for your business. You could of course write to the store manager direct yourself without any intermediary, saying that your mother wishes to claim and asking him to pass it to his insurance company - it's hard work pursuing a claim on your own though, but it can be done. I'll be interested to hear what other ABers might say on this one - it's been some years since I worked in an insurance claims department!
