I had a problem some years ago as I always received a check from abroad (first from Kenya then from the USA when my friends moved there). The bank had always cashed these, though their cut took a large proportion. For the past few years the banks have refused to cash cheques under a certain amount so I thanked the sender for their kindness over the years but told them that I could no longer cash the cheques, as I realised they would probably notice if they weren't cashed. I had thought, and indeed hoped, that this would be the end of it, but now they send sterling.
