Your cake will be presented in a sturdy cake box with a lid, therefore if you are collecting the cake yourself, please ensure it is transported in the boot of the car or on the floor (the footwell) of the car, as the transport surface needs to be flat.
Allowing someone to carry the cake on their lap is not secure or a good idea, as the driver may have to break suddenly and in this event your cake is likely to become damaged.
In order to get the most portions out of your cake, you should always cut the cake in rows and columns, never from the middle outwards as rows and columns is the protocol used by cake designers when they are approximating the number of people a cake will feed.
If in the unlikely event you have any cake left after your celebration, always make sure the cut end is covered with cling film/foil in order for the cake to retain its moisture.
You should not place the cake in an airtight container as this will cause the icing to sweat and become sticky and tacky. All my sponge cakes will last for approximately 5 days from the date you are in receipt of them, but will dry out sooner if not protected from the elements once cut as advised above.
If you have a keepsake cake topper from your cake, please do not place it in the fridge or an airtight container as the condensation will make is sweat. Keep it dry by simply placing it in a box, cupboard or on a shelf, but ensure that is it away from direct sunlight as the sun will make it warp and the colours will fade!
