50/50 sop for me when i get my shoe swab due to my not taking off my orthopedic shoes tho i can't figure out which 50% is the sop

in the op's case, i'm gonna say it falls into the realm of the tso's randomly patting you down just after you go thru the wtmd as they have recently been doing at sfo (which imho, is just act DXII of the play )


n.b. if one is concerned about a hand swab and something giving a false positive (such as a combination* of hair gel, nicotine, cologne, etc), stop at the restroom and wash your hands throughly before going thru security. <--100% sop for me


*and before i get jumped on by a tso for saying the items i mentioned will not alarm, n.b. i said combination as the items i mentioned by themselves do not set off any alarms but there will be times where "ingredient a" combined with "ingredient b" will set off the bells and whistles
