'I ordered the floral arrangement for the funeral service. I realized that I had omitted a name from the card. I called this morning to rectify the situation; I didn't hear back from the florist, so I assume "no news is good news" and the name was added. Thank You.'
'I TRUST YOU DID A GREAT JOB MAKING UP THE ARRANGEMENT. THANK YOU FOR YOUR HELP IN GETTING THIS TO THE FUNERAL HOME ON SHORT NOTICE.'
'Thank you so much for your excellent service and communication. I would highly recommend your services! Thanks again.'
