How to stop multiple touches from occurring?

I have a script that teleports you and clones a GUI into the player when the player touches a part. However, theres always multiple GUI's being cloned. I've tried to stop this with a debounce, but it wouldn't work. I'm not sure if I'm doing something wrong.

local seats = game.Workspace.room1.seats:GetChildren()
local exitgui = script.Parent.exitgui
local debounce = false

script.Parent.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		if debounce == false then
			debounce = true
			local player = game.Players:GetPlayerFromCharacter(hit.Parent)
			for i,v in pairs(seats) do
				if seats.Occupant == nil then
					hit.Parent.Humanoid.JumpPower = 0
					hit.Parent.Humanoid.WalkSpeed = 0
					script.Parent.slam:Play()
					exitgui:Clone().Parent = player.PlayerGui
					player.Character.HumanoidRootPart.CFrame = seats[math.random(1,10)].CFrame 
				end
			end
		end
	end
end)		

You forgot to set the debounce to false

local seats = game.Workspace.room1.seats:GetChildren()
local exitgui = script.Parent.exitgui
local debounce = false

script.Parent.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") then
        if debounce == false then
            debounce = true
            local player = game.Players:GetPlayerFromCharacter(hit.Parent)
            for i,v in pairs(seats) do
                if seats.Occupant == nil then
                    hit.Parent.Humanoid.JumpPower = 0
                    hit.Parent.Humanoid.WalkSpeed = 0
                    script.Parent.slam:Play()
                    exitgui:Clone().Parent = player.PlayerGui
                    player.Character.HumanoidRootPart.CFrame = seats[math.random(1,10)].CFrame 
			wait(1)
			debounce = false
                end
            end
        end
    end
end)        

There is quite simple solution for that. Instead of having debounce you put line that checks if there is already a gui inside of player. So it will look like this:

local seats = game.Workspace.room1.seats:GetChildren()
local exitgui = script.Parent.exitgui
 
script.Parent.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") then
            local player = game.Players:GetPlayerFromCharacter(hit.Parent)
            for i,v in pairs(seats) do
                if seats.Occupant == nil then
                    hit.Parent.Humanoid.JumpPower = 0
                    hit.Parent.Humanoid.WalkSpeed = 0
                    script.Parent.slam:Play()
						  if player.PlayerGui:FindFirstChild"exitgui" then
							player.Character.HumanoidRootPart.CFrame = seats[math.random(1,10)].CFrame
						else
                    exitgui:Clone().Parent = player.PlayerGui
                    player.Character.HumanoidRootPart.CFrame = seats[math.random(1,10)].CFrame
						end
               end
           end
      end
end)
