Free flowers

I went into Waitrose today. The woman who supervises the self checkout tills is quite stern. I always make a point of thanking her. I must have worn her down because today she gave me a free bunch of flowers as I was leaving and smiled at me. Waitrose give the out of date flowers away. These look perfectly fresh and haven’t even opened out. There was no label on them. Do they look like Alstroemeria.
