In the UK, free-pour of spirits is not common. Most bars use optics, a picture of one is here.
If the bar has a large range of spirits, the less frequently used ones may be poured into a measuring glass (a small steel cylinder), before being put into the customer's glass.
I haven't seen optics or measuring glasses being used in The States, are they common?
