When you visit the tower, bring biscuits. Expecially if your visiting today between 10.30 & 18.00 ;-)
If you are Brian from EGBO then biscuits will be available on Thursday and possibly Friday next week.
What remains available on Friday will all depend on how many are left after the FI's have descended on them like a plague of locusts but I'm open to bribery to save you a few.
