Multiliguists of Lemmy - When speaking Language A and using a word from Language B how do you decide which pronunciation to use?

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

\ • What sort of restaurant
\ • Who you’re dining with
\ • Who you’re ordering from
\ • and probably a lot more…
