I leave a sae padded envelope with label ----- cleaning, Customers used to send either a cheque or cash.
From November through to January I lost over £500 by someone in the postal service opening the envelopes and stealing the cash.
I reported it and it stopped from Feb until the other day when two envelopes arrived one of which had £10 missing and the other was a cheque.
I changed my slips to instruct cheques only but some customers still send cash.
Too far away to go collecting.
Will be reporting it again and looking for a full investigation to catch the thief.
Obviously some clever postal worker has worked out that the padded envelopes sometimes contain cash, paid for his Christmas!
