I knew someone who got a retail job in Seattle. They were coaching employees to refuse to sell large quantities of things to scalpers. Like someone buying ten pairs of jeans at a go, to fly out of SEATAC to someplace Levi’s are expensive.
Levis (jeans in general) were such a hot commodity on the black market there, that the number of pairs of jeans in his luggage was written on his entry stamp in his passport, and when he exited the country, he had to have the same number of jeans.
