How do I freeze a player during an animation?

So, In my game I have a coffee machine, and when the player puts the mug in it, it fills it up with coffee. I need a way to freeze the player while the fill-up animation is playing. I've tried anchoring the gear but that didn't work. I need a script that will take the player inserting the mug and freeze during the animation. Here is my current script.

script.Parent.Touched:connect(function(h)
    if h.Parent.Name == "Mug" then
        h.Parent.Name = "Waiting"
        script.Parent.Parent.tea.Transparency = 0
        wait(3)
        script.Parent.Parent.tea.Transparency = 1
        h.Parent.Name = "Tea"
        h.Parent.tea.Transparency = 0
    end
end)
