The next incident was 8.40pm on January 11 and resulted in about $450 allegedly being stolen.
The final incident was about 4.30pm on January 20 where $400 was allegedly taken.
The store had upped its security as a result.
"We started locking the doors in the evening at 5pm and only buzzing in customers in if they didn't look threatening," Chhikera told Fairfax.
Chikkera was concerned for the store's future, however.
"We feel unsafe, and can't afford a security guard at $1000 a week, that's not how much money a franchisee makes.
"Staff are so panicked and stressed and they don't end up making any money anyway."
A Police spokeswoman confirmed police were investigating the three robberies.
