Refactoring

Entire refactor needs to be done to move all logic out of the main loop and into functions. Something along the lines of:

void loop() {
    readInput();
    updateDisplay();
    dispsenseTickets();
}

void readInput() {
    // do something to read the input
}

void updateDisplay() {
    // do something to update the display with # inputted
}

void dispenseTickets() {
    // do something to dispense the tickets based on the # inputted
}
