Erk. Class B clearance must always, always, always, always (always) be
given explicitly with "... cleared to enter the Class Bravo
airspace...". Any other usage isn't an implied clearance.

You can get implied clearance through C and D space if they use your
full callsign, but B is the big special 80,000 lbs. gorilla, and needs
full, explicit clearance.

As to the OP, technically speaking it was mostly your responsibility to
get the clearance, but both parties were really at fault, and no real
harm came because of it, so I wouldn't worry too terribly much.
