They said on the news tonight that the deal ( ie money they are giving ) with the company that produces CO2 in England is only for three weeks, after that it stops. As it will take them two weeks to get production started again, we might be back to aquarium one very soon!
On the topic of lettuce, I have always wondered why people eat it, it hardly fills you up! I saw a poster which had bowls containing various varieties of salad stuff and veg, the amount in each bowl was the amount you need to eat to get the same nutritional value eg six cherry tomatoes, one apple etc. The bowl of lettuce was huge, like a washing up bowl, no one could eat that much at one sitting. So as I’m not a fan of eating lettuce, I stopped buying it there and then!
