Got my ass mocked for not being able to speak Cantonese as a ipoh Chinese malaysian

Hope y'all read this cuz why not lmao

Was working part time at a booth when a bunch of cina uncles (three) came by my booth. They were conversing in Cantonese with one another, nothing extraordinary. I asked one of the uncle if he wanted to try the product (Bluetooth speaker) in Mandarin. As soon the words left my mouth the uncle gave me a grimace and said:"huh?" Lmaoo Idk why but my dumb ahh asked him again this time in Malay since most malaysians should know Malay and he turned to his friend and said out loud "dude doesn't know Cantonese lol " (something like that la ) and I understood since I knew a little canto

For extra info im quite white washed and I usually speak English with my friends but Chinese with my family so my Chinese is so so but English is my strongest language. Malay is so so as well

Yeah that's it just wanted to share my experience
