During my ten years as a publican I was always made very aware that trading standards were just as much against giving the customer too much as too little, so it crossed my mind this morning - just who counts the seeds in the packets, not many actually say "approx **** seeds" & what if they sneezed while counting.......!
You need to get out more!
Here's another quandry, which type of seeds produces the most produce per packet?
Could it be giant pumpkins where you get say 5 seeds per pack or maybe cabbages where you get hundreds of seeds per pack, etc etc....
That could be a question for Stepen Fry & the QI teams
