It's considered somewhat outdated and potentially offensive to use this phrase in modern French society, as it can be perceived as disrespectful and condescending.
It's much more polite and appropriate to use a more modern phrase like:
* "Excusez-moi" (Excuse me)
* "Monsieur/Madame" (Sir/Madam)
* "S'il vous plaît" (Please)
* "Je voudrais..." (I would like...)
When addressing a waiter or server, it's best to be respectful and use polite language.
