Corkage fee for a cake!

So, I made a booking at HQ restaurant for my birthday and on booking, they told me that I had to pay a R80 deposit per person for a booking of 12 people or more. So I paid the R960 which is refundable. Its a week later and I have not heard anything from HQ and no refund paid yet.<br> <br> Then, when I received my bill, they charged me R300 \corkage"for my the birthday cake I brought in! Have you ever in your life heard of a corkage fee for a cake! Not to mention that they don't even offer cake on their menu. I understand that with wine you have to pay corkage because that is something the restaurant offers. But birthday cake"
