Most of the Services companies (telecom, insurance, credit cards etc) have their Monthly Cheque’s collected through various means like NetBanking transfers, Cash Paid at the branches, People collecting them from your home / office.
But they also place their Cheque drop boxes at various locations (mostly in some shops in the neighbourhood), these at times are not very safely placed or you’re not too comfortable in dropping your cheques and worried about the service getting suspended because of the cheque not reaching safely. One such example here.
