Sure it is heat and crowds and crying kids around and this is why they sell WINE. No, seriously, everyone have bad days but not everyone shoots people around. Some people just out of control,that is all. I worked for a bank years ago, when this woman came and wanted to deposit check several days before its date. We were not allowed to do it without a manager permission and she refused.This woman got ballistic on me, she was cursing and screaming. If she could reach me she would start a fight. Imagine how I felt.
