ADVICE please :)

Hello ladies. 
So I need some advice.. idk which topic to put this in. So sorry if it's in the wrong one. 
Okay. 
I told my boss about my sister that she is looking for a job, so then my boss interviewed her and then hired her.. 
My sister starts on Wednesday... However, literally 5 seconds later some clinic that she applied for called her saying that she got the job!! 
My sister is studying to be a nurse... so she wants to work at the clinic however doesn't want me looking bad because I was the one who recommended her to my boss. 
I told my sister that it's fine, that the clinic will give her more experience since she is studying to be a nurse. But deep down, I feel embarrassed because I know it's gonna make me look bad since my sister is going to deny the job at my work. We need a PO clerk asap! So she's basicallly going to leave them hanging ): 
Ah! What do you girls think ?? What are your opinions? 
Thank you :)
