Wasps in a high traffic area are definitely bad, but if the nest is somewhere not too in the way I'd encourage folks to leave it be. Wasps are predators, and they eat a lot of the bugs that damage gardens. Yes, they are also assholes, do you have to strike a balance, but they can be really beneficial.
Obviously, if you've got young kids around or the wasps are being aggressive, take care of the humans first, but understanding them a bit can really reduce the conflict with them.
