Security check was unreasonable with carry on bag that contained shampoo and perfume in bottles that exceeded regulated limits. I argued that both containers did not exceed the ML limit as they were both half empty. Also the perfume was previously purchased as duty free, which I did bring on another plane. They forced me to check in my bag which nearly caused me to miss my flight. Her conduct was inn-appropriate in not providing me with her full name and being reasonable with the ML limits.
