text: The ones most people miss are the nice little old ladies with a clutch purse held tightly against her midsection, people in wheelchairs, & baby strollers, & obese people & pregnant women.   Also suspicious are people who stand in line & keep going back to other isles to exchange items for other things.  Somewhat absent-minded, yet with no real purpose.  Many security guards mistake people on perscription medications for people on street drugs just by the way they are dressed.  It's not fair, but it happens.  Do you fit into any of these categories?
