When do you use a pronoun with "po"?
Here are some sample sentences:
1) Kamusta po kayo sir? (How are you sir?)
2) Puwede po bang pakihintay sir? (Is it possible to wait sir?)
In 1) a pronoun and po are both used. In 2) only a pronoun is used. Are there any guidelines for this?
Could you say:
Puwede po ba ninyong pakihintay sir? (Is it possible for you to wait sir?)
