how many of you do those side jobs for the Thieves Guild that involves the same city,and/or a different person or the same just a different objective?

For Example:
you do a burglary job in Whiterun say in Ysolda's House and after you complete that job you do a sweep job only to find out that IT MAY be the same person just a different objective

and i know it can lead to extra coin but after awhile doesn't get frustrating

oh where it says "but a objective" it suppose to say: "but a different objective"
