Questions & Answers about Sin que tú lo pidas, la camarera trae agua gratis a la mesa.

Why is pidas in the subjunctive after sin que?

Because sin que introduces a hypothetical/negative event that hasn’t happened (“without X happening”), which triggers the subjunctive. Here the subjects are different (tú in the subordinate clause vs. la camarera in the main clause), so you need sin que + subjunctive. If the subjects were the same, you would use sin + infinitive instead.

Could I say Sin pedirlo instead? Does it mean the same?

No, it changes the subject. Sin pedirlo, la camarera trae… means “Without asking for it, the waitress brings…,” i.e., the waitress doesn’t ask. To say “without you asking,” you need sin que (tú) lo pidas.

Can I drop tú, or is it necessary?

You can drop it: Sin que lo pidas is perfectly natural. Including tú adds emphasis or contrast (“without you—specifically—asking”).

What does lo refer to here? Shouldn’t it be la because agua is feminine?

Here lo is a generic, catch‑all direct object pronoun meaning “it,” very common in the set phrase sin que lo pidas (“without you asking for it”). If you want to tie the pronoun directly to a specific agua, you can use la—especially when the water is definite: Sin que la pidas, la camarera trae el agua. Avoid le here; pedir takes a direct object for the thing asked for.
