I really have no idea why the techs carried them but not the pharmacists;
The techs packs mostly contained a digital blood pressure machine (I don't call them sphygmomanometer's as they technically aren't), peak flow tester and a number of those damn Cialis sponsored alcohol-gel spray bottles. I swear that the branded drugs freebies have become a compulsory requirement to get NICE approval these days.
I know what you mean about proper pharm knowledge, one that gets me is I had to explain to my own Pain consultant about how Tramadol is worthless to take in a person who is on Ondansetron or similar 5HT3 antagonist. I don't expect consultants to be encyclopedias but a little pharmacology brush-up in their subject area every once in a while wouldnt go amiss.
I find the best way to deal with it is to imagine you can impart the knowledge directly into their brain via a rather heavy copy of Martindale's
