Yup it could be a simple coincidence that an EV related Chinese company (Jinbo-ZJMY) has a potential rivals product right outside their store.
Pretty sure there is NO similarity between your coffee shop and Tesla. They are like apples and oranges. In fact apples and oranges are still fruits, so that's still too similar in your case.
In any case, I am happy to think that it's a coincidence until I'm proven wrong!
