re: Cake drop-off without anyone to sign for it

Ditto Jonathan. I take lots of pics…for same reason
Also, I contact the bride to be, wedding organisers and venue manager, kitchen controller, ahead of time to get clearance for access, table, where it’s going etc, assembly, cutting instructing, refrigeration etc. so far, I’ve been lucky with full co-operation from all parties.
I had one delivery problem for a birthday cake to a London upmarket restaurant, who refused the cake to go to the kitchen, but compromised and allowed it to be stored in a cool side room and followed my instruction, via a diagram as well as verbal, for them to assemble…. Scary, but Thank goodness it went off without a hitch.

You must never limit your challenges, instead you must challenge your limits
