Vending machine (darkrp)

Hi again, im running an HL2rp and today i was in want of making a coffee machine so i did it but when a player buy the coffee it claim him 20tk (money), and then all the coffee are free for everyone.

This is my code

	function ENT:SalePrice(activator)
	local discounted = math.ceil(20)

	 
		-- If they are still a cook, sell them the food at the discounted rate
		if self.allowed and type(self.allowed) == "table" and table.HasValue(self.allowed, activator:Team()) then
			return discounted
		else -- Otherwise, sell it to them at full price 
			return math.ceil(20)
		end
		end
	

	
	function ENT:Use( activator, caller )
		self.user = activator
	if not activator:canAfford(self:SalePrice(activator)) then
		DarkRP.notify(activator, 1, 3, DarkRP.getPhrase("cant_afford", string.lower(DarkRP.getPhrase("food"))))
		return ""
	end

	if activator.maxFoods and activator.maxFoods >= GAMEMODE.Config.maxfoods then
		DarkRP.notify(activator, 1, 3, DarkRP.getPhrase("limit", string.lower(DarkRP.getPhrase("food"))))
	elseif not self.Once then
		self.Once = true
		self.sparking = true

		local discounted = math.ceil(20)
		local cash = self:SalePrice(activator)

		activator:addMoney(cash * -1)
		DarkRP.notify(activator, 0, 3, DarkRP.getPhrase("you_bought", string.lower(DarkRP.getPhrase("food")), DarkRP.formatMoney(cash)))  return
			end

		if delay_can == false then
		local ent = ents.Create( "canette" )
	
		activator:EmitSound( Sound( "ambient/levels/labs/coinslot1.wav" ) )
		ent:SetPos( self:GetPos() + ( self:GetForward() * 30 ) + ( self:GetUp() * -30 ) )
		ent:SetAngles( self:GetAngles() + Angle( 0, 0, 90 ) )
		ent:Spawn()
		ent:Activate()
		ent:GetPhysicsObject():ApplyForceCenter( self:GetForward() * 150 )
		delay_can = true
		timer.Simple( 3, 	function()
							delay_can = false
							end )
		end 
	
	end
	 
	function ENT:Think()
	end
 
 
 
 return
end

A little bit long to read.

Thank all for help.

Check your self.Once, you only allow it to be called once because you set it to true.
