They sure can, I just don’t think they would, unless the person was acting oddly. They probably were though, because I assume that’s their shtick, but just dressing up in cosplay but otherwise acting normally probably wouldn’t bother most people behind the counter.
obviously not in their right min
That really depends on context. If the person was otherwise behaving normally and had a reasonable explanation for how they’re dressed (i.e. they’re coming back from comicon or something), I don’t see why not, as long as the background checks out.
Then again, if they come in filming the place and whatnot, then yeah, I wouldn’t touch that with a 10’ pole. That’s a lot more sus than some makeup.
