I get that it's a CYA on Amazon's part but it also puts other people at risk. There are limited ambulances and if they are always running to the Amazon warehouse for some triviality, someone seriously injured or having a stroke or heart attack somewhere else could have to wait longer.
I wonder if there is a technicality in the wording. It says "Ambulances have been called out" or "called to" it doesn't say they "attended" the warehouses.
999 operators will triage and prioritise ambulances based on the symptoms being exhibited.
Even worse, it happens at some nursing homes for anything worse than a bandaid.
"You have nurses! Even moreso, you're charging the patient/their family for '24/7 Nursing Care!'", meanwhile grandma has a slightly swollen foot and you're calling 911 to CYA or be lazy.
That is a valid criticism but it seems like a criticism of Britain's health care system. When people and organizations can have access to free ambulances and healthcare and the costs are paid for by others, the demand goes way up.
