[Avodah] Trying to understand the rationale for Pas Yisroel when eating an Oreo

[Avroham Yakov]

Shana tova all!

The main point of Pas Yisroel is because of chasunos.  Obviously, if I cook
my cholent and other food in for example Mrs. O’Leary’s house, I will become
quite friendly with them.

But when eating an Oreo, or any other commercial type of product, what is
the rationale that it should be Pas Yisroel?

Thank you,

Avroham
