I actually stole my first enema bag when I was 15 or 16 years old. It was a small town grocery store, and before security cameras, bar codes and RFID chips. You just had to make sure no one was looking.
Over the years I bought from drugstores, and learned to buy when an older lady was the cashier. They always seemed to understand. Sometimes they would lean across the counter and ask in a low voice things like "do you need some lubricant?" or "you know you have to use ivory soap with this, right?"
I have a thing for old Mom & Pop drugstores found in small towns, mostly right on the square. I found one of these drugstores about 20 years ago and asked the young lady behind the counter where they kept their enema equipment. We were the only ones in the store, except for the old gray-haired pharmacist who I imagined was her father. She took me over to the isle where the enema bags were, but then showed me a selection of colon tubes and bakelite nozzles kept behind the counter. She was very knowledgable about the subject.
I purchased several colon tubes and a number of nozzles from her saying that I lived in the city and couldn't find these items where I lived. She instructed me to not use petroleum-base products on the colon tubes and suggested I purchase some mineral oil for lubrication. Something tells me this young woman had experienced many enemas.
The only time any one ever said anything out of the ordinary was when I was in a drugstore and saw one of the old blue pumpkin bags which doubled as both an ice pack and an enema bag. I knew I couldn't pass up this purchase no matter who was at the cash register. When I walked up to the counter, a fairly young guy who was clearly more feminine than masculine rung up the sale. As I turned to walk away, he said "have fun!" The reason this comment was out of line was because the other items I had just purchased were items to treat a winter flu.
Another way to deal with the embarrassment of shopping for enema equipment is to write a list of what you want to buy and hand the list to one of the employees, telling them this is what the doctor told you to pick up. The sad fact is that there are not many Mom & Pop drugstores around these days. The new drugstores are nothing but big-box stores like Home Depot with no personality at all.
