The bakery said to save on cost, they can make cake to feed 20 people then for the rest of 30 of them- have a sheet cake… but how do they do it? do they make their cake- and then put the sheet cake underneath so it all looks like together? or do they feed the 20 people, then go get a sheet cake- and serve that up??

They will have the 2-tier wedding cake out in the reception hall for all to see, and keep the sheet cake in the back to simply cut and serve.
