さよなら as goodbye? (Kansai)

I thought it wasn't really used like that, cause it's more permanently goodbye? But people have said it to me at the employment centre for example. I wondered if they were implying 'I hope I never see you again' (either as 'because you're annoying' or 'because hopefully you find a job'), or they were just saying it to me because they thought I'd understand better. But I also heard a family I walked past say it, it looked like the kids were going to school or something.

So is it actually used sometimes like 'goodbye' in English?
