The best examples that come to mind are when ordering food. As examples:
• You speak English and Spanish and are ordering a burrito
• You speak Thai and English and are ordering Tom Yum
I imagine it could depend on numerous things:
• You primary language or ethnicity
• What sort of restaurant
• Who you’re dining with
• Who you’re ordering from
• and probably a lot more…
It depends.
Let’s say I’m trying to ask an acquaintance their phone number so I can add them on WhatsApp or Signal. Honestly it’s kind of ridiculous to use the proper pronunciation of Whatsapp im Brazil, so I use the popular way (it’s something like “oah-tchi-zap”).
Unless I’m actually speaking with someone in their mother language I just default to the Brazilian version of the name. Otherwise I will try and match their pronunciation - it’s nice to train and also I think it’s polite.
