Velma had no trouble getting the prophylactics made.  Though it did take the large part of the day. Velma feels like it's enough time for her to deliver them to a rivaling tavern with an inn, the top two floors of which were the apartment of the shonite sisters.  The trick was to deliver them and not get drawn into a three way with the two beautiful women, or quite possibly more, since they weren't shy about having company.  Maybe she'd get lucky and they weren't there.  Then again, it wasn't like her father NEEDED her help exactly.
