Mete tu billete en el validador.
Meaning

Cultural Tip
In most Spanish‑speaking cities, paper tickets must be validated before you board. The validator (often a small box with a slot) stamps or lights up the ticket to show it’s been used. Forgetting to do this can result in a fine, so locals will often remind tourists with this exact phrase. In some regions, contactless cards are used instead, but the wording stays the same for paper tickets.
