On christmas day, the weathermen where calling for 12-16"of snow, with snow coming down 2-3a' an hour. I bill out in 8" intervals. Which means I did everybody twice. Unfortunately the weathermen where a little off we got 8". I charged everybody for two billings and had no complaints. The other night I was plowing and was chewed out by two people for coming twice for the last snow storm. I know both of them are cheap, but should I have billed twice for this particular strom?
