there are lots of buildings here that have crappy messenger-only rules. like the "deliveries in rear" sort of thing, forcing messers down dark alleys to truck-intended loading docks. or the "no bags" rule, where you have to leave your bag (and all your crap) at the front desk with some crappy guard who could care less if it gets stolen. Or, there's my favorite, the "no tools" rule that some government office buildings have, where you have to leave your allen wrench at the front desk (so they can lose it for you).
It's almost worse knowing that I can skirt these rules since I'm not a messenger. I mean, what makes me any different? It's crappy that anyone has to put up with that.
