That is just not true. Nowhere can you be happy-go-lucky about the contracts you sign. Even where there is a degree of protection for consumers like in Sweden, and I wouldn't just assume that everything will work out fine even then, b2b is very caveat emptor.

> I did, so can you.
He did, maybe you won't be so lucky, get a local lawyer.
