A name is something the reader needs to keep track of, so the role itself might be alright, but context is usually everything.
Having a full character workup on that character can certainly help in giving non-standard reactions to what your primary characters are up to. “Reminds me of my sister” or similar. However, that might be overboard for the needed role, so you could instead mention “They paid.” and simply move on, even cutting out that minor character all together. Of course, you can still have a character workup for them and never drop the name too.
If you’ve got two or three minor characters interacting in a slightly more significant way, now you have to differentiate them, so you could always go “blond” vs “black” haired, or use names or their roles or something else; though names require a way to get them, or fast nicknames (as I did in one scene where Hermione “nicknamed” them in her head, just to keep them straight).
