I just found a bonus/lucky card with 10 pieces of wood - thanks Happy Meeple!

In the beginning I figured out (with help from others) that with a
Grocery (6 pieces of wood) one's able to buy food in units smaller than 4 - a single food portion. (Not that a game will be cheaper itself.) I rarely have used this because mostly I can wait a few minutes until the counter reached zero and gave me a new unit or I took 38 coins at once.
What I really would enjoy: When it's been possible to buy
magic food in portions smaller than one day! For example half a day or eight hours or four hours (or even smaller).
I rarely have time to play 24 hours at a strech (only when I got my first magic potion "1 day"-lucky card

) so it would be really nice to use a grocery to buy small(er) units of magic potion for a few hours "excessive" play of single player games or a bunch of 'expensive' games (e.g. Carto).
Thanks for all the great games here!
