is 9k as a waiter good pay?

okay so recently i interviewed for service position at a cafe in bandra and the owner said she would pay me 9k monthly and I have to work 9 hour shift 6 days a week. this will bemy first job and I told her I'm only looking to work for summer and she agreed but im sort of a bit worried that she's paying me less (i asked other waiter there and she didn't specify how much she was being paid but she did say it was more that 9k) is this a good offer? please help
