They were in our garage at the old house, in all the time i was in the old house i saw them out in the open maybe twice, i would have to hunt to find them, they stay out of the way and just get on with keeping flies and insects at bay, i would clean out the shells of the dead insects now and again, as they went through hundreds!
The only real issue i would say is that their webs were a bit lower and in some instances, head height, so maybe not a nice thing to walk into if you didn’t know they were around, i know they’re not ‘medically significant’ bites, but meant to be as bad as a wasp/bee sting, so i’d rather avoid being bitten. I guess the guy with the leg issue had an allergy, same with people stung by wasps, he probably also left it until very late to seek medical attention.
