This is the really interesting idea but if you are thinking about how to do it, there is no need to direct competition but it can be someone who comes in to see if this shop is really that good as they were told.

It could be something similar to that masochist girl torture but maybe a slightly different reaction where she complains instead of simply enjoying that and wants to try something different instead.
Something like tsundere masochist who does not admit her feelings directly.
