forgot to add i used flavoured syrups, ie raspberry, marshmallow, irish coffee etc.... some folks, specially my sis in law, used to like hot frothy milk with raspberry syrup in it..... and some folks like coffees with flavours in. Your coffee supplier should be able to supply these aswell as your coffee beans, we used cafe creme for espresso etc, and we ground them on the premises.
If you are serving hot lunches too, make sure you keep the salt and peppers where you are. They will get nicked!!!....
