A pensioner died after being locked in a Debenhams toilet - a day before she was due to celebrate her golden wedding anniversary.
Lorraine Rawbone, 70, suffered a fatal blood clot after using the toilets in the Falkestone store at the end of the day on March 31.
But staff failed to notice she was there - and she was only found hours later after her husband Terry used his Find My iPhone app.
The couple had been married for 50 years and were due to celebrate their golden wedding anniversary the following day.
Police officers struggled to gain access to the building before she was spotted - unconscious but breathing.
A post-mortem found Mrs Rawbone died of pulmonary embolism - an often fatal blood clot.
Pathologist Dr Salim Anjarwalla said the pensioner would have had a greater chance of survival had she been treated sooner - but the outcome might have been the same.
A Debenhams spokesman said: "We wish to extend our sincere condolences to the family.
"The coroner's concerns have been noted by our health and safety team."
