They annoy me but I don't have any problems with them. They don't cause me any stress.
I don't think they are making us any safer.
Airport security world wide has the bad impact of giving fairly low paid and uneducated people power and they can get carried away with it.
I was passing through Panama and I was the only passenger entering the check zone. They had the usual zig-zag of pillions and tape. I walked up close to the end and opened the tape and went to the front about 10' away.
The bozo said "You didn't go through the line."
I pointed out that there was nobody in the line.
He said "But you have to go through the line."
"Why there is nobody there, I am not cutting in front of anyone."
"He called another worker over they conversed in Spanish, thinking that I don't speak Spanish."
guy 1 "This man didn't go through all the line he just came to the front."
guy 2 "There isn't anyone else waiting."
guy 1 "I know that but I want to see him go through the lines."
guy 2 turned to me and said "Sir you need to go back and go through the line."
I went through the lines and they checked me through.
Me "los dos están locos sin clases." (You are both fools with no class) I walked away leaving them gawking, realizing that I understood everything they had said.
Telling a Latino that they have no class is a powerful insult beyond what the same words implicate in English.
