I had to pick up my sister's wedding cake up years ago and transport it to the venue. I put it in the back of our van and stationed my daughter and two of her friends to hold onto the base. I then drove 14 miles verrrrrry, verrrrry slowly, especially around corners. I was a nervous wreck. Then we had to slide it out and roll it in on a cart. I can guarantee you I'd gladly pay the delivery fee for someone before I'd do THAT again. Maybe you can offer to pay the fee as a wedding present?
I watch wedding shows sometimes (what can I say....I'm female) and it amazes me what the brides and grooms will quibble about paying. They spend $50,000 on a wedding/reception and get their undies in a twist about a $50 delivery fee.
