Gender neutral greetings

Just wondering if you know of a gender neutral greeting for someone you don’t know? Like- costumer things. My ‘script’ my mom taught me has me saying things like “Excuse me, miss, but I can’t find ___,” or “excuse me, sir,” or ma'am or mister. is there a gender neutral version of this?

The only thing I can think of is just leaving off miss/sir entirely. Eg “Excuse me, but I can’t find ____.”
I think that isn’t usually seen as rude.
Do any of y'all have another suggestion?
