[Ethereum] Expected token LParen got Identifier

I am currently trying to build a simple Process in Solidity, but somehow I get the Error: Expected token LParen got Identifier for the function WaiterBringsPizza and CustomerReceivesPizza. I'd be very thankful if anyone could help!

pragma solidity ^0.4.16;
contract RestaurantMASTER{
event logStatus(uint orderNumber, bytes input, uint256 timestamp);

//Initialize State-variables(!)
function RestaurantMASTER(){
tokens[0]++;
CU = Customer(newCustomer());                       //[0] @contracts
WA = Waiter(newWaiter());                           //[1]
CH = Chef(newChef());                               //[2]
DB = dataBase(newDataBase());                       //[3]

}

    //Contract 'Objects'
    address[] public contracts;
    Customer CU;
    Waiter WA;
    Chef CH;
    dataBase DB;


    //Casual State-Variables
    int[] public tokens = new int[](7);
    uint public orderNumber = -1;

        CU = new Customer();
        contracts.push(CU);
        return (CU);
    }
      function newWaiter () private returns(address newContract) {
       WA = new Waiter();
        contracts.push(WA);
