Not the person you asked, but a native Spanish speaker myself. The formal way to say “excuse me” (for example to a teacher or boss, or to a stranger on the street if you wish to be polite) would be “disculpe señor/a”, or “discúlpeme señor/a”. You can also remove señor/a and simply say “disculpe” or “discúlpeme” to anyone and it will still carry the same meaning, since the verb in both cases already implies it’s about yourself. The informal way would be “disculpame” or “discúlpame”, although in this case adding señor/a sounds way off. You can definitely add a name though, ie, “discúlpame Shads” and that would be okay.

You know the more I reflect on this the more sure I am that I am falling into a trap that I am sure a lot of English speakers fall into. I am trying to apply English rules to Spanish as there is a shared language root and a bunch of shared words and at some level syntax. I need to acknowledge that Spanish is a distinct mature language and trying to treat it as a different dialect of English is a wall I need to stop butting my head off. Really appreciate you stepping in to clarify for someone with my calcified language abilities, the lack of comprehension is entirely my own. I think I will go with “Por favor, apila las sillas al final del día. Gracias.” and save deeper understanding until I can devote more time and mental energy to understanding Spanish as Spanish. You rock!
