Decades aho, my first Saturday job was in a florists, and I've always tried to support local shops wherever I've lived. However flowers? I give up.
A while ago a friend was poorly, a few of us chipped in a fiver each. I went to the local florist, explained the situation, said I'd leave the choice to her, and pick them up in the morning. Tgey were wrapped ordinarily, looked fine, but when the friend's husband put them in a vase, I was so embarrassed. It was just a few stems. I'd have been embarrassed if they'd just come from me, but this was a group gift.
Now? Local M&S or Waitrose are near, and nice for a gift. But most supermarket flowers last well and look good.
