Had a business meeting in Chelmsford yesterday. Could have sworn it was at 11:30. When I turned up the receptionist said the chap I was to meet was in the Colchester office. While she was frantically trying to contact him, I looked at the email from last week again and was horrified to read; "Before 11:30 or after 14:30." Luckily the chap my contact wanted me to see was working from home some 10 minutes away and I had a meeting with him instead. Day saved! Must learn to read emails properly.
