Last night at about 9PM in the dark there was a knock at the front door. People never seem to see the door bell. It was this dairy guy asking me if I'd like him to deliver milk. I politely asked him if he could tell the time, he said "Sorry" and cleared off. If this had been 5 or 6 VERY big lads intent on no good I could have been in trouble, even though I'm a big guy.
Question is: Are these door chains that can be screwed into PVC doors and frames any good? I can't see the screws holding out against a good kick.
Thanks
