"Well there's the fact that if you go three months without a contract, you either get shuffled together with someone random or your designation switches." Which wouldn't necessarily be a problem for some people, but Nepeta doesn't really think being a submissive would agree with Sollux.

"Fur us with the mark, though, it does make it a lot easier to pick things up from some stores if we can say that we're contracted. Some places won't sell to us anyway, but I've mostly figured out which ones are that obnoxious about it. Fur Dominants, I'm not sure, except what I said earlier about being switched to submissive. Some of them like having somebody to boss around, maybe?"

That would fit with this place. Though it really does make her hope some of their mutual acquaintances don't ever show up here...
