Now, I know that you feed your vendors. However, I am sure throughout the night someone is bound to get thirsty! We are having an open bar for our guests and then we pay a different price per child. My question is, do you pay the price of the open bar for the vendors or do you pay for them to get non-alcoholic drinks like you do for the children? I am not sure on the etiquette on your vendors beverages and I have searched everywhere! Thanks!!
