All About Your Travelling

There is one airport where there are people just before you get to the security lines (not sure if they are TSA or airport employees) who demand that you only have two bags. I travel with a Rolling Computer case and a knapsack and a purse. There is always room for the purse in the knapsack, but until I no longer need access to my ID, I keep it out.

In NO OTHER AIRPORT does anyone challenge me on the fact that I have three bags visible, but at this one airport, they always do, and they get quite obnoxious about it, even when I open the knapsack and show them the gaping space meant for the purse.

I would really like to be able to tell them to leave me alone, as they interrupt my getting-organized (keys and Cell Phone in this pocket, iPod in that pocket, Boarding Pass and ID here, coat, shoes, computer and Toiletry Bag out). But I want to be able to tell them with authority.

Thanks in advance.
