So, we all know now that everywhere in the US, the laptop has to come out of the case, and be stuck into a Grey Laundry Tub. Anywhere other than LaGuardia one’s shoes must go into a Grey Tub (at LaGuardia they yell at one for befouling the Tubs with shoes and they must go straight on the belt – but at JFK and Newark they admonish one for putting shoes on the belt). It’s a subtle dance of security lines that only experience can adequately choreograph.
