I was wondering that above sentence on title, “Excuse me, Ms.” is rude or not. I’ve watched a video on youtube about English titles, but “Excuse me lady.” is very rude to get attention from women, and “Excuse me ma’am” is good for southern part of the U.S. whereas it sometimes feels uncomfortable in other area. I know that Sir. can use for all men regardless of age. I need native English speaker’s correct and clear answer. Thank you !
