What is the volume of a tot liquor?

There isn't a standard volume for a "tot" of liquor. The term "tot" is often used to describe a small amount of liquor, but the exact quantity can vary depending on the context.

Here are some examples:

* Historically: In the navy, a "tot" of rum was often measured as 1/8th of a gill (about 1.25 fluid ounces).

* Modern usage: Today, a "tot" might refer to a shot (1.5 ounces), a small pour (1 ounce), or even just a sip.

* Contextual: The size of a "tot" might also depend on the type of liquor being served and the occasion.

To avoid confusion, it's best to be specific when referring to the amount of liquor you want. For example, instead of saying "a tot of rum," you could say "a shot of rum" or "a small pour of rum."
