is it a case of trolly attendants only doing it as an alternative to door knocking--but realising its a lot harder than they thought ?
after all--its easy to stand on a door step for ages if no-ones at home--then slowly creep to the next house---only to be told to leave.
but standing in a public place----to be approached by all and sundry--that takes some balls. then up comes an apostate----!!! i can understand why they ran away.
