hah.. my bro in law works in a pharmacy and I asked if they carry glycerin, and he asked why and I told him for my e-juice and he replied "I wouldn't smoke that sheit it's a suppository" haha...
but in all fairness since I'm in the medical field also, If you go into a Pharmacy and you ask for stuff like that, they won't know what you are really asking for and your intent so yeah, no point in calling them idiots they are basically doing their jobs. Honestly, just try going to Michael's they sell Wilton glycerin in the baking area or online.
I wasn't referring to people who asked "suppositories?" are idiots? They ARE just idiots in general! Don't know about walmart in your neck of the woods, but around here, they ARE absolute IDIOTS! Even the pharmacists behind the counter -- IDIOTS -- their manager --> him2!
