Finnish phonology differs greatly from that of other languages.  Just like the rolled r doesn’t exist at all in many Asian languages, b, g & d are usually “fused” with p, k & t, while c, f, q, w, x and z are only used for loanwords.

This means that on rare occassions you might end up with a guy who think’s he’s saying “grabbed” sounding like “crapped” instead.  As any other accent, you just get used to it.
