I really, really would like to know the town you live in.
I can not imagine the scenario you say happen-my friend owns a Flower Shop and a driver would be canned for pulling such a trick. No way any reputable business owner would condone that at all.
Unless a driver took them for themselves?
UPDATE on the stolen funeral flowers:
I decided to go ahead and call the funeral home yesterday afternoon. The director in charge of my neighbor's funeral wasn't there, so I talked with a lady who I presume was an office employee. I told her that I was calling to let them know what happened, that I wasn't calling on my neighbor's behalf as she didn't want to pursue it, and that I didn't want the deceased's family bothered with the issue. I just thought they should get a "heads up." Yes, I was very polite.
The lady told me that over 90 arrangements (wow!) were delivered for the funeral. Anyway, she said that they take photos of all the arrangements before the visitation and give these photos to the deceased's family in a remembrance book. From my description of the arrangement, she was able to find the picture on her computer. She said that they take any business/condolence cards off each arrangement before photoing it, then put the cards back on after. In her photo, the green orchids ARE missing. She was very quiet for a moment, then said she'd never heard of anything like this happening before. She had her doubts that a delivery person would know the value of the orchids (really?...hmmm), but she couldn't refute my theory that a delivery person probably took them. She was kind of dumbfounded herself.
So, there you have it. I have no proof, but there just isn't any other logical explanation. The theft happened before the arrangement had been taken from the garage into the funeral home to be photoed and placed for visitation.
So yes, I do believe there is a nonreputable florist in the area, with a driver who knows flowers and their value, and who WOULD condone such a theft. I would venture that 99.99999% of all arrangements are made by and delivered by florists. The deceased's family has no idea what flowers the arrangements are SUPPOSED to have in them.
There's a crook around every corner, my dad used to say.......
