Good salespeople are trying to connect customers with solutions that provide them value that they otherwise wouldn't have access to (generally because they weren't aware of it). Obviously, in practice, the line between that and the more negative experiences can be fuzzy and vary by one's perspective, but unless you have someone in-house who's dedicated to searching for new solutions... And then, they turn into a sort of salesperson themselves, with ambiguous allegiances. At least someone from the outside is someone you will always be skeptical about.
