If you opened a second Indian restaurant in a small town in New-Zealand (population 20,000), it would one hurt the first Indian restaurant’s business.
If a larger town in New-Zealand (population 200,000) has just 1 Indian restaurant, opening a second one helps both restaurants. More people in the town are likely to try and embrace Indian cuisine and the quality of food in both restaurants is likely to go up.
Competition isn’t always to be feared. Oftentimes, it is to be embraced.
