How to handle heckler?

Hi y’all! I’m planning to perform some multilingual tunes in April at my residency gig. I’m bilingual, on route to tri, and have solid basics in other languages. I look European and my name is pretty unique.

Well, a few nights ago at my residency, I was 3 songs into my set, and on the 4th I did a Spanish song, “Burbujas de Amor”, the audience loved it and I had several people stop for the song and one couple dance. But one lady was not very happy and requested “no more español por favor”. I told her no worries then started singing “The Scientist”, which definitely went over her head. Although I had thought to just play another Spanish one, she was pretty drunk and didn’t want to deal with escalation.

I was taken aback, and since I’m planning that multilingual night in April, I would like to be more confident in case this happens again. I mostly do English at this venue, but there are tons of other speaking guests/tourists that come as well. I would appreciate the help on some responses I can have prepped for future hecklers. 🙏🏼 thanks in advance
