Let me modify the example to make the legal situation more clear. The butcher creates the packs in the morning. The customer comes in the afternoon and sees the packs with the weights and prices. The customer picks a pack, takes it to the till and pays for it. Yes the law has been broken. The customer could have been mislead and disadvantaged. It does not matter whether a misleading statement is in grams or pounds. It is still an offense. If the customer could be mislead but not disadvantaged, it is not an offense. If the pack said 1 lb, 200 g then the customer gets more than they paid for. As I understand it.
