My text label doesn't add text automatically and doesn't close automatically after text?

What I want is, when I click my button, the GUI pops up (Which it does) but the text does not appear, and after the text I want the GUI to automatically close. Here is the script:

local p = game.Players.LocalPlayer

script.Parent.MouseButton1Click:connect(function()
    game.ReplicatedStorage.Cheezburger:Clone().Parent = p.Backpack
    script.Parent.Parent.Parent.Waiter.ImageLabel.Visible = true
    script.Parent.Parent.Parent.Waiter.Frame.TextLabel.Visible = true
    script.Parent.Parent.Parent.Waiter.Frame.Visible = true

    wait(1)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "E"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "En"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "Enj"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "Enjo"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "Enjoy"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "Enjoy Y"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "Enjoy Yo"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "Enjoy You"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "Enjoy Your"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "Enjoy Your M"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "Enjoy Your Me"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "Enjoy Your Mea"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "Enjoy Your Meal"
    wait(0.2)
    game.StarterGui.Waiter.Frame.TextLabel.Text = "Enjoy Your Meal!"
    wait(3)
    game.StarterGui.Waiter.ImageLabel.Visible = false
    game.StarterGui.Waiter.Frame.TextLabel.Visible = false
    game.StarterGui.Waiter.Frame = false
end)

There are no errors in the console. Hope you can help! :)
