What's the worst thing you have ever sent to someone either by text or email. About 3 weeks ago I was working on a quotation for a client, there was a lot to it so I had 2 worksheets, one with the figures, the other with my costings and margins, of course that's the feckin one I ended up sending the client, luckily my figures were alright because I still got the contract but I know next time it's going to come back and bite me.
