Burnt toast and car exhaust?

[Wynterz]

I bought my first orchid, a Phal, three days ago or so. When I smelled it then it smelled like car exhaust, not very strong, but still. Today, it smelled different, like burnt toast. Is there something wrong or is it supposed to smell funky? I read that Phals don't usually have a scent so I'm wondering. Any advice or suggestions would be much appreciated.
