Venue change

You have a contract with the venue under the original coordinators, right? Go back to that contract, and see what is spelled out specifically. Just because someone new takes over, does not mean that your contract terms change. If you find that there is nothing in the contract about extra charges for the grooms cake, you need to contact these new people and tell them that your contract says "xxxx" and make them honor that. That is the whole point of a signed contract. Someone new cannot come in and change everything without your approval, consent, and a new signed contract.

Please don't let these people walk all over you. It would not be in their best interest to sabotage your day, because word of mouth spreads really fast, so do reviews, so they want to keep you happy--even if they won't admit it. Look at your contract again.

I encourage you to THOROUGHLY REVIEW the contract. Does it mention anything about transfer of responsibility? Are extra charges for the cake listed in the contract, or does it mention the cake at all? If the extra charges are NOT in the contract, tell them tough luck, but you get what you were initially promised, a filled cake with a simple design.

So I could potentially see where this is coming from. Are they talking fruit fillings or just buttercream? Fruit fillings or even like crumbles of cookies or something are usually extra at any bakery (at least the ones I talked to). Just flavored buttercream as the filling was not extra. I am not sure why it would be an extra $40 for the groom's cake though when it says included in your contract. So I would ask them about both, be up front and mention the contract!!
