I don't understand why you would need to do anything to get the ring off. All of the rings that have been fitted for me come off no problem. If they have to lubricate it to get it off, maybe they need the next size up!

That's gross, though. Kind of reminds me of all the bad things you have to deal with when working retail. For me, it was people coming in and urinating/defecating/vomiting in the dressing rooms. Not all of them were homeless. The things that people do disgust me. Also, touching things or doing things before handing me money.
