Dude, I've met these people. Shit is real, except they travel in shitty conditions(crowded van), sleep in shittier conditions(crowded hotel rooms), and its annoying having these people come to your home/apt/whatev.
Funny story about one of these people:
Me and my friends were all getting blazed in my apt when some chick with a thick Tennessee accent came selling subscriptions. We invited her in and she gave us a speil trying to hustle up magazines, but I'm pretty sure she knew she wasnt gonna get through to us, so eventually we get to making small talk and she eventually asks what we were smoking (like she didnt know). We got her high and talked for a bit more, and then somehow the topic of undercover cops came up. She instantly took the oppertunity to say she was an undercover DEA agent and there was a van outside waiting for us. Scared the dickens out of my roommates, me too for a second, but then i realized she got high with us, and it was pretty much impossible, seeing as she wasnt the first magazine person to come around. Anywho, after we all calmed down we chatted some more then she went on her way.
