Ye, at the time the Cinema flyer guy actually did read the signs and we got the flyer, but almost no other flyers.
The mailman proper, if I can call them that, did however deliver all stamped mail no matter what. The "no adds"-sign does not work for stamped adds, or like flyers put into the newspaper, etc.
Oh yeah I wouldn't expect the mail carrier to make a judgement call on when I want mail if my name and address was on an envelope. But for the flyers from supermarkets and things that get stuffed into every mailbox should really respect the "no flyers" sticker. Ah well, it's only a minor inconvenience in the end
