Tips for purchasing food and drink for a talk
While cookies, donuts and chocolate are always a safe bet, I have seen that fruits and vegetables are highly appreciated as well. They are really cheap, but require some work, as apples, stem cabbages, peppers ... have to be cut into pieces of finger food size. Cutting and preparing plates for 50 people takes something between 30 and 60 minutes, depending on whether you just want to serve food or have a nice presentation as well.
