[UnNethack] Black market friendlies

So my stash is located on the same level as the portal to the black market, and I was making a lot of trips in and out while I had a pet dragon inside. But while I was doing this, one of the friendly nymphs walked out, and I mistook it for an enemy and killed it outside in the regular dungeon. Will this have angered one eye Sam and the rest of the market? Should I be prepared for iron bars to come slamming down the moment I step back in there? Honestly after looking at Sam's equipment I may just not go back in at all if that's the case.
