It's random. My shorts button set off the alarm and OMG I was treated like a criminal, seriously. The security must have wanted to impress someone. He yells at me to put hands up and turn around slowly. So I thought maybe it was my credit card that set it off. So I ask him. He yells again, just keep hands up and turn slowly. He comes at me with wand and wands me. It goes off at my waist area and he tells me to slowly lift up my shirt. He wands again and sees it was the metal button on my shorts. I have never had that happen before with any of my shorts. I was embarrassed the way he yelled. Had I not been with my family, I would have complained to guest services. I understand they have a job to do and I am all for the metal detector. I think everyone should be scanned. On same token, when it's set off, not everyone is a criminal and should not be treated as one to impress your peers or show other guests that you don't play. There was no need for him to raise his voice at me. He could have just requested me to put hands up and turn slowly instead of yelling for all around to hear
