Buggy OnTouched GUI event with fast deleting and not showing when still?

Alright, this is hard to comprehend but I'll try to the best of my abilities to explain it. So, essentially I wanted something based off NBA 2K, where there is a basketball court, and 6 spots per court. 3 for each team, as people get on the spots they have a GUI show up that says "Join spot" so that they can get next in line to play on the court for the next game.

I have the on-touch GUI working to the point where everything is OK besides there's this thing that it removes from my PlayerGUI back and fourth a lot and bugs out. I'd get on the spot and it would disappear and reappear 20 times a second and there's also a predicament where if I stand still, the GUI doesn't show even though I am still on/in the block in which is suppose to trigger it on touched.

I tried adding wait(3) and wait(2) to try to slow the script down and prevent this but it keeps happening. Here's the script:

(Don't mind the middle part. It's just to color the GUI to the color of the spot's team they are trying to join, red or blue)

local Gui = game.Lighting.EnterBlueSpot

function GiveGui(Player)
	if Player.PlayerGui:FindFirstChild(Gui.Name)~=nil then return end
		Gui:Clone().Parent=Player.PlayerGui
		wait(2)
	end

	local Player=game.Players:GetPlayerFromCharacter(hit.Parent)

	if Player==nil then return end

	GiveGui(Player)

	Player.PlayerGui.EnterSpot.RoundedButtonThing.RoundedBG.Frame.BackgroundColor3 = Color3.new(0,255,255)
	Player.PlayerGui.EnterSpot.RoundedButtonThing.RoundedBG.Frame2.BackgroundColor3 = Color3.new(0,255,255)
	Player.PlayerGui.EnterSpot.RoundedButtonThing.RoundedBG.Corner.ImageColor3 = Color3.new(0,255,255)
	Player.PlayerGui.EnterSpot.RoundedButtonThing.RoundedBG.Corner2.ImageColor3 = Color3.new(0,255,255)
	Player.PlayerGui.EnterSpot.RoundedButtonThing.RoundedBG.Corner3.ImageColor3 = Color3.new(0,255,255)
	Player.PlayerGui.EnterSpot.RoundedButtonThing.RoundedBG.Corner1.ImageColor3 = Color3.new(0,255,255)
end)

script.Parent.TouchEnded:connect(function(hit)
	wait(3)
	local Player=game.Players:GetPlayerFromCharacter(hit.Parent)
	if Player==nil then return end

	Player.PlayerGui.EnterBlueSpot:Destroy()
end)
