How to add a debounce to this script so the player does not spam?

I have a script where players touch a part with tools. I want to add a debounce so the player has to wait before giving it another tool. Can anyone help me with this?

oats = 0
print(oats)
local Allowed = false

function tch(h)
if (h.Parent.Oats.Name == "Oats") then
    oats = oats + 1
    h.Parent:Destroy()
    print(oats)
end
end

script.Parent.Touched:connect(tch)

local Allowed = false

function give(dough)
    if Allowed == true then
        local y = dough.Backpack
        local z = game.Lighting["Handful of Oats"]
        z:Clone().Parent = y
        oats = oats - 1
        Allowed = false
    end
end

function onClicked()
if oats > 0 then
    Allowed = true
end
end

script.Parent.ClickDetector.MouseClick:connect(give)
script.Parent.ClickDetector.MouseClick:connect(onClicked)
