I have been out lately door knocking and stumble across a few shift working folk sleeping the day. Feel quite bad at getting out of bed. I decided to to make up for this bad business practice.I made a door hangers with my business name on saying" I am a shift working and sleep during the days Please don`t knock. If you leave a leaflet or note, I will read it later.Thank you." If I awaken any of these people I will give them a door hanger.Which is a good will gesture and good advert for me.
