The key thing that most pharmacists don't understand is that to have a compensation case you have to have suffered a 'loss'. This means a siginificant discomfort e.g. death or a bad reaction. If someone somes back with the wrong tablets, which they haven't taken where's the loss? Nobody can 'sue' for the cost of having to return to the pharmacy. The majority of people, in my experience are ok if you apologise profusely.
However you can always rely on the Pharm Soc to persue you. I know of one case where someone was done because they didn't put a PIL in the packaging.
