I worked in a corner store underneath a housing assistance block. All the customers were either alcoholic, disabled, drug addicted, demented, very elderly, or all of the above.

One guy lifted his top, and showed me his recent heart surgery, which immediately started bleeding once he took the gauze off. I had a lot of instances of them showing me their weird medical ailments, actually. This particular customer was a pathological liar, but reportedly had once murdered a man. He was now approaching dementia, but sometimes attempted to use his dementia to not pay for booze.

The worst, but funniest, was this infamous customer called James. He had inherited a fortune and spoke poshly, but was now a seemingly demented alcoholic. Just hangs around the village charmingly harassing people. Kind of a local myth type character.

One day he comes in and starts calling me common muck and all this other stuff, says he could buy the entire shop, and so on.

Another customer was there, who was friends with all the staff, and also a posh old alcoholic (but still totally functioning outwardly), starts defending the staffs honour. The two old men get into a shouting match. Then it escalates so they're now both whacking each other with walking sticks. We split them up. James gets banned from the store. As he leaves, he does a big diarrhea shit mostly in his pants but a little bit on the floor.

The boss kindly opted to clean it up for me, given that it was my first few days on the job.
