One large franchise owner would have the role of developing a certain number of
restaurants in a particular region over a period of time, putting up their own capital to do so and perhaps subfranchising to individual owners.
It's commonly believed that it was first whipped up
in Indian
restaurants in the UK (Glasgow
in particular is often cited), but many argue that it was first influenced by dishes from the Punjab
region of India and Pakistan well before it appeared
in UK
restaurants.
